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, Figure 9-5) is to broad-
cast data by the software protocol.
In Master mode, the data is transmitted/received as
soon as the SSPBUF register is written to. If the SPI
module 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
applications as a “line activity monitor”.
The clock polarity is selected by appropriately program-
ming bit CKP (SSPCON<4>). This then, would give
waveforms for SPI communication as shown in
FIGURE 9-2:

Figure 9-6, Figure 9-8 and Figure 9-9, where the MSb is
transmitted first. In Master mode, the SPI clock rate (bit
rate) is user programmable to be one of the following:
• F
/4 (or T
)
OSC
CY
• F
/16 (or 4 • T
OSC
• F
/64 (or 16 • T
OSC
• Timer2 output/2
This allows a maximum bit clock frequency (at 20 MHz)
of 5.0 MHz.
Figure 9-6 shows the waveforms for Master mode.
When CKE = 1, the SDO data is valid before there is a
clock edge on SCK. The change of the input sample is
shown based on the state of the SMP bit. The time
when the SSPBUF is loaded with the received data is
shown.
