ic_slv_data_nack_only
Generate Slave Data NACK Register
The register is used to generate a NACK for
the data part of a transfer when the I2C module is
acting as a slave-receiver.

Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

| 0 | nack | Generate NACK. This NACK generation only occurs when the I2C module is a slave-receiver. If this register is set to a value of 1, it can only generate a NACK after a data byte is received; hence, the data transfer is aborted and the data received is not pushed to the receive buffer. When the register is set to a value of 0, it generates NACK/ACK, depending on normal criteria. 1 = generate NACK after data byte received 0 = generate NACK/ACK normally Reset value: 0x0
