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 the BF bit (SSPSTAT<0>) is set or the SSPOV bit
(SSPCON<6>) is set.
An SSP interrupt is generated for each data transfer byte. The SSPIF flag bit must be cleared in
software, and the SSPSTAT register is used to determine the status of the byte.
