RECEPTION
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 overow condition exists, then
no acknowledge (ACK) pulse is given. An overow con-
dition is dened 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.
