EXAMPLE 2:

LOOP BTFSS SSPSTAT, 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 2 for sample code.

When the AD clock source is selected as 2 T
RC (when ADCS2:ADCS0 = 000 or x11), the E
(Integral Linearity Error) and E
Linearity Error) may exceed the data sheet
specification at codes 2047, 2048 and 2049.
Work around
Select the AD clock source as 4 T
16 T
2 T
