8.3.1.2
When the R/W bit of the address byte is clear and an
address match occurs, the R/W bit of the SSPSTAT reg-
ister 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 con-
dition is defined as either bit BF (SSPSTAT<0>) is set
or bit SSPOV (SSPCON<6>) is set.
An SSP interrupt is generated for each data transfer
byte. Flag bit SSPIF (PIR1<3>) must be cleared in soft-
ware. The SSPSTAT register is used to determine the
status of the byte.
