7.5.1 TUSB564-Q1 I2C Target Behavior

TUSB564-Q1 I2C Write with Data Figure 7-2 I2C Write with Data

Use the following procedure to write data to TUSB564-Q1 I2C registers (refer to Figure 7-2):

  1. The controller initiates a write operation by generating a start condition (S), followed by the TUSB564-Q1 7-bit address and a zero-value “W/R” bit to indicate a write cycle.
  2. The TUSB564-Q1 acknowledges the address cycle.
  3. The controller presents the register offset within TUSB564-Q1 to be written, consisting of one byte of data, MSB-first.
  4. The TUSB564-Q1 acknowledges the sub-address cycle.
  5. The controller presents the first byte of data to be written to the I2C register.
  6. The TUSB564-Q1 acknowledges the byte transfer.
  7. The controller can continue presenting additional bytes of data to be written, with each byte transfer completing with an acknowledge from the TUSB564-Q1.
  8. The controller terminates the write operation by generating a stop condition (P).

TUSB564-Q1 I2C Read Without Repeated Start Figure 7-3 I2C Read Without Repeated Start

Use the following procedure to read the TUSB564-Q1 I2C registers without a repeated Start (refer Figure 7-3).

  1. The controller initiates a read operation by generating a start condition (S), followed by the TUSB564-Q1 7-bit address and a zero-value “W/R” bit to indicate a read cycle.
  2. The TUSB564-Q1 acknowledges the 7-bit address cycle.
  3. Following the acknowledge the controller continues sending clock.
  4. The TUSB564-Q1 transmit the contents of the memory registers MSB-first starting at register 00h or last read register offset+1. If a write to the I2C register occurred prior to the read, then the TUSB564-Q1 shall start at the register offset specified in the write.
  5. The TUSB564-Q1 waits for either an acknowledge (ACK) or a not-acknowledge (NACK) from the controller after each byte transfer; the I2C controller acknowledges reception of each data byte transfer.
  6. If an ACK is received, the TUSB564-Q1 transmits the next byte of data as long as controller provides the clock. If a NAK is received, the TUSB564-Q1 stops providing data and waits for a stop condition (P).
  7. The controller terminates the write operation by generating a stop condition (P).

TUSB564-Q1 I2C Read with Repeated Start Figure 7-4 I2C Read with Repeated Start

Use the following procedure to read the TUSB564-Q1 I2C registers with a repeated Start (refer Figure 7-4).

  1. The controller initiates a read operation by generating a start condition (S), followed by the TUSB564-Q1 7-bit address and a zero-value “W/R” bit to indicate a write cycle.
  2. The TUSB564-Q1 acknowledges the 7-bit address cycle.
  3. The controller presents the register offset within TUSB564-Q1 to be written, consisting of one byte of data, MSB-first.
  4. The TUSB564-Q1 acknowledges the register offset cycle.
  5. The controller presents a repeated start condition (Sr).
  6. The controller initiates a read operation by generating a start condition (S), followed by the TUSB564-Q1 7-bit address and a one-value “W/R” bit to indicate a read cycle.
  7. The TUSB564-Q1 acknowledges the 7-bit address cycle.
  8. The TUSB564-Q1 transmit the contents of the memory registers MSB-first starting at the register offset.
  9. The TUSB564-Q1 shall wait for either an acknowledge (ACK) or a not-acknowledge (NACK) from the controller after each byte transfer; the I2C controller acknowledges reception of each data byte transfer.
  10. If an ACK is received, the TUSB564-Q1 transmits the next byte of data as long as controller provides the clock. If a NAK is received, the TUSB564-Q1 stops providing data and waits for a stop condition (P).
  11. The controller terminates the read operation by generating a stop condition (P).

TUSB564-Q1 I2C Write Without Data Figure 7-5 I2C Write Without Data

Use the following procedure to set a starting sub-address for I2C reads (refer to Figure 7-5).

  1. The controller initiates a write operation by generating a start condition (S), followed by the TUSB564-Q1 7-bit address and a zero-value “W/R” bit to indicate a write cycle.
  2. The TUSB564-Q1 acknowledges the address cycle.
  3. The controller presents the register offset within TUSB564-Q1 to be written, consisting of one byte of data, MSB-first.
  4. The TUSB564-Q1 acknowledges the register offset cycle.
  5. The controller terminates the write operation by generating a stop condition (P).

Note:

After initial power-up, if no register offset is included for the read procedure (refer to Figure 7-3), then reads start at register offset 00h and continue byte by byte through the registers until the I2C controller terminates the read operation. During a read operation, the TUSB564-Q1 auto-increments the I2C internal register address of the last byte transferred independent of whether or not an ACK was received from the I2C controller.

Software must only access (read or write) addresses detailed in this document. Accessing reserved or undocumented addresses can result in TUSB564-Q1 entering an undefined state.
