RECEPTION

When the R/W bit of the address byte is clear and an

address match occurs, the R/W bit of the SSPSTAT

the SSPBUF register.

When the address byte overflow condition exists, then

no Acknowledge (ACK) pulse is given. An overflow

condition is defined as either bit BF (SSPSTAT<0>) is

set, or bit SSPOV (SSPCON<6>) is set. This is an error

condition due to the user’s firmware.

An SSP interrupt is generated for each data transfer

byte. Flag bit SSPIF (PIR1<3>) must be cleared in

software. The SSPSTAT register is used to determine

the status of the byte.
