When the A/D clock source is set as 2 T
or RC, the Integral Linearity Error and Differ-
ential Linearity Error may exceed the data
sheet specification, in extremely rare cases,
at codes 511 and 512.
When configured for I
MSSP module may not receive the correct
data if the SSPBUF register is not read
within a window after an SSPIF interrupt
occurs
