SBAS495D June 2010 – August 2021 PCM9211
PRODUCTION DATA
The PCM9211 supports two types of control interface, which are set using the MODE pin (pin 27), as defined in Table 7-33.
MODE | MODE CONTROL INTERFACE |
---|---|
Tied to DGND | Two-wire (I2C) serial control |
Tied to VDD | Four-wire (SPI) serial control |
The input state of the MODE pin is only sampled during a power-on reset or external reset event. Therefore, any change after device power on or external reset is ignored.
Table 7-34 shows the pin assignments based on the control interface selected.
PIN | DEFINITION | |
---|---|---|
SPI MODE | I2C MODE | |
23 | MDO | ADR0 |
24 | MDI | SDA |
