When operating in Enhanced Buffer Master mode,
the Transmit Buffer Full flag, SPITBF, may be
cleared before all data in the FIFO buffer has
actually been sent. This may result in data being
overwritten before it can be sent.
This has only been observed when the SPI clock
prescalers are configured for a divider of greater
than 1:4.
This behavior has not been observed when the
module is operating in any other mode.

Framed SPI modes as described in the device data
sheet are not supported. When using the module,
verify the FRMEN bit (SPIxCON2<15>) is cleared.
All other SPI modes function as described.
Work around
None.

If possible, use a total clock prescale factor
of 1:4 or less.
Do not use SPITBF to indicate when new
data can be written to the buffer. Instead,
use the SPIRBF or SPIBEC flags to track
the number of bytes actually transmitted.
If the SPITBF flag must be used, always
wait at least one-half SPI clock cycle before
writing to the transmit buffer.

PORTA pin, RA0, may not operate correctly as
an input when the open-drain output is enabled
for PORTB pin, RB0 (ODCB<0>). RA0 will
operate correctly as an output.
Work around
None.
Affected Silicon Revisions
Once
(AD1CON1<15> = 1), it may continue to draw
extra current even if the module is later disabled
(AD1CON1<15> = 0).
Work around
In addition to disabling the module through the
ADON bit, set the corresponding PMD bit
(ADC1MD, PMD1<0>) to power it down
completely.
Disabling the A/D module through the PMD reg-
ister also disables the AD1PCFG registers,
which in turn, affects the state of any port pins
with analog inputs. Users should consider the
effect on I/O ports and other digital peripherals
on those ports when ADC1MD is used for power
conservation.
