Table 24-1 lists the pins associated with the I2C interface.
Signal | Device Level Signal | I/O(1) | Description | Reset Value |
---|---|---|---|---|
SCL | i2cj_scl(2) | I/O | I2C serial clock line. Open-drain output buffer. | 1 |
SDA | i2cj_sda(2) | I/O | I2C serial data line. Open-drain output buffer. | 1 |
SCL | i2ci_scl(3) | I/O | I2C serial clock line. Emulated open-drain output buffer. | 1 |
SDA | i2ci_sda(3) | I/O | I2C serial data line. Emulated open-drain output buffer. | 1 |
For the i2cj_scl and i2ci_scl signals to work properly, the INPUTENABLE bit of the appropriate CTRL_CORE_PAD_x registers should be set to 0x1 because of retiming purposes.
The path from a module pin to device pad(s) is defined at the device I/O logic level. The I/O logic maps the module signals to the different pads of the device and is programmable in the Control Module registers. Refer to the sections Pad Functional Multiplexing of the chapter Control Module, for more information.
