2. Module: MSSP (SPI Mode)

FIGURE 1:

EXAMPLE 1:

LOOP BTFSSSSPSTAT, BF

When the SPI is using Timer2/2 as the clock

source, a shorter than expected SCK pulse may

occur on the first bit of the transmitted/received

data (Figure 1).

Work around

To avoid producing the short pulse, turn off Timer2

and clear the TMR2 register, load the SSPBUF

with the data to transmit and then turn Timer2 back

on. Refer to Example 1 for sample code.
