When the R/W bit of the incoming address byte is set and an address match occurs, the R/W bit
of the SSPSTAT register is set. The received address is loaded into the SSPBUF register. The
ACK pulse will be sent on the ninth bit, and the SCL pin is held low. The transmit data must be
loaded into the SSPBUF register, which also loads the SSPSR register. Then the SCL pin should
be enabled by setting the CKP bit (SSPCON<4>). The master must monitor the SCL pin prior to
asserting another clock pulse. The slave devices may be holding off the master by stretching the
clock. The eight data bits are shifted out on the falling edge of the SCL input. This ensures that
the SDA signal is valid during the SCL high time
An SSP interrupt is generated for each data transfer byte. The SSPIF flag bit must be cleared in
software, and the SSPSTAT register is used to determine the status of the byte transfer. The
SSPIF flag bit is set on the falling edge of the ninth clock pulse.
As a slave-transmitter, the ACK pulse from the master-receiver is latched on the rising edge of
the ninth SCL input pulse. If the SDA line was high (not ACK), then the data transfer is complete.
When the not ACK is latched by the slave, the slave logic is reset and the slave then monitors for
another occurrence of the START bit. If the SDA line was low (ACK), the transmit data must be
loaded into the SSPBUF register, which also loads the SSPSR register. Then the SCL pin should
be enabled by setting the CKP bit.
