Slave Mode
In slave mode, the SCL and SDA pins must be configured as inputs (TRIS bits set). The SSP
module will override 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)
In this case, the SSPSR register value is not loaded into the SSPBUF, but bit SSPIF and SSPOV
bits are set.
tus 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 the SSPOV bit 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 (SSPCON<6>), was set before the transfer was received.
