13.12.2
When the R/W bit of the address byte is clear and an
address match occurs, the R/W bit of the SSPSTAT
register is cleared. The received address is loaded into
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 of the SSPSTAT
register is set, or bit SSPOV of the SSPCON register is
set. This is an error condition due to the user’s firm-
ware.
An SSP interrupt is generated for each data transfer
byte. Flag bit SSPIF of the PIR1 register must be
cleared in software. The SSPSTAT register is used to
determine the status of the byte.
