TRANSMISSION
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 pin RC3/SCK/SCL is held
low. The transmit data must be loaded into the SSP-
BUF register, which also loads the SSPSR register.
Then pin RC3/SCK/SCL should be enabled by setting
bit CKP (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 stretch-
ing 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 (Figure 8-9).
An SSP interrupt is generated for each data transfer
byte. Flag bit SSPIF must be cleared in software, and
the SSPSTAT register is used to determine the status
of the byte. Flag bit SSPIF 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 ACK is latched by
the slave, the slave logic is reset (resets SSPSTAT reg-
ister) and the slave then monitors for another occur-
rence of the START bit. If the SDA line was low (ACK),
the transmit data must be loaded into the SSPBUF reg-
ister, which also loads the SSPSR register. Then pin
RC3/SCK/SCL should be enabled by setting bit CKP.
