Slave Mode
In slave mode, the SCL and SDA pins must be configured as inputs (TRIS 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 the SSPIF and SSPOV
bits are set.
tus of bits BF and SSPOV. The shaded cells show the condition where user software did not prop-
erly clear the overflow condition. Flag bit BF 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
