The SSP module has five registers for I
• SSP Control Register (SSPCON)
• SSP Status Register (SSPSTAT)
• Serial Receive/Transmit Buffer (SSPBUF)
• SSP Shift Register (SSPSR) - Not directly accessible
• SSP Address Register (SSPADD)
The SSPCON register allows control of the I

The SSPSTAT register gives the status of the data transfer. This information includes detection
of a START or STOP bit, specifies if the received byte was data or address, if the next byte is the
completion of 10-bit address, and if this will be a read or write data transfer.
The SSPBUF is the register to which transfer data is written to or read from. The SSPSR register
shifts the data in or out of the device. In receive operations, the SSPBUF and SSPSR create a
doubled buffered receiver. This allows reception of the next byte to begin before reading the last
byte of received data. When the complete byte is received, it is transferred to the SSPBUF reg-
ister and flag bit SSPIF is set. If another complete byte is received before the SSPBUF register
is read, a receiver overflow has occurred and the SSPOV bit (SSPCON<6>) is set and the byte
in the SSPSR is lost.
The SSPADD register holds the slave address. In 10-bit mode, the user needs to write the high
byte of the address (1111 0 A9 A8 0). Following the high byte address match, the low byte of
the address needs to be loaded (A7:A0).
