When the master device wants to terminate
receiving any more data from the slave device, it
will do so by sending a NACK in response to the
last data byte received from the slave. When the
slave receives the NACK, the R/W bit of the
SSPSTAT register remains set improperly.
Work around
Use the CKP bit of the SSPCON register to
determine when the master has responded with a
NACK. The CKP bit will be clear when the
response is an ACK, and set when the response is
a NACK. The CKP bit is automatically cleared to
stretch the clock when the master responds to
received data with an ACK. This gives the slave
time to load the SSPBUF register before setting
the CKP bit to release the clock stretching. When
the master responds to received data with a NACK
the CKP bit properly remains set, and there is no
clock stretching.
