Master Mode
The master can initiate the data transfer at any time because it controls the SCK. The master
determines when the slave (Processor 2,
tocol.
In master mode the data is transmitted/received as soon as the SSPBUF register is written to. If
the SPI is only going to receive, the SDO output could be disabled (programmed as an input).
The SSPSR register will continue to shift in the signal present on the SDI pin at the programmed
clock rate. As each byte is received, it will be loaded into the SSPBUF register as if a normal
received byte (interrupts and status bits appropriately set). This could be useful in receiver appli-
cations as a “line activity monitor” mode.
The clock polarity is selected by appropriately programming the CKP bit (SSPCON1<4>). This
then would give waveforms for SPI communication as shown in
