RECEPTION

When the R/W bit of the received address byte is clear,

the master will write data to the slave. If an address

match occurs, the received address is loaded into the

SSPBUF register. An address byte overflow will occur

if that loaded address is not read from the SSPBUF

before the next complete byte is received.

An SSP interrupt is generated for each data transfer byte.

The BF, R/W and D/A bits of the SSPSTAT register are

used to determine the status of the last received byte.
