 DLN_RESULT DlnI2cSlaveDisable(
    HDLN handle,
    uint8_t port,
    uint8_t waitForTransferCompletion
 );

The DlnI2cSlaveDisable() function deactivates the specified I2C slave port at your DLN-Series adapter and releases pins previously used for SDA and SCL lines.

Parameters:

handle

A handle to the DLN-series adapter.

port

A number of the I2C slave port to be disabled.

waitForTransferCompletion

If you call the DlnI2cSlaveDisable() function during the I2C transfer, PC-I2C slave adapter can either wait for transfer completion or deactivate the module immediately. Use the waitForTransferCompletion parameter to specify whether PC-I2C adapter must cancel the transfer or wait for transfer completion:

DLN_I2C_SLAVE_WAIT_FOR_TRANSFERS(1)	wait for transfer completion
DLN_I2C_MASTER_CANCEL_TRANSFERS(0)	cancel all pending data transfers and deactivate the module

This function is defined in the dln_i2c_slave.h file.
