Slave Mode
In slave mode, the SCL and SDA pins must be configured as inputs. The SSP module will over-
ride the input state with the output data when required (slave-transmitter).
When an address is matched or the data transfer after an address match is received, the hard-
ware automatically will generate the acknowledge (ACK) pulse, and then load the SSPBUF reg-
ister with the received value currently in the SSPSR register.
There are certain conditions that will cause the SSP module not to give this ACK pulse. These
are if either (or both):
a)
b)
If the BF bit is set, the SSPSR register value is not loaded into the SSPBUF, but the SSPIF and
SSPOV bits are set.
the status of the BF and SSPOV bits. The shaded cells show the condition where user software
did not properly clear the overflow condition. The BF flag bit is cleared by reading the SSPBUF
register while bit SSPOV is cleared through software.
The SCL clock input must have a minimum high and low time for proper operation. The high and
low times of the I

The buffer full bit, BF (SSPSTAT<0>), was set before the transfer was received.
The overflow bit, SSPOV (SSPCON1<6>), was set before the transfer was received.
