4. Module: SPI (Enhanced Buffer Mode)
5. Module: Core (Low-Power BOR)
DS80474B-page 4
In Enhanced Buffer mode (SPI1CON2<0> = 1),
polling the SPI Transmit Buffer Full bit, SPITBF
(SPI1STAT<1>), may produce erroneous results.
This occurs only under two circumstances:
•
•
For Master mode, this includes all combinations
of the primary prescale bits (SPI11CON1<1:0>)
and secondary prescale bits (SPI1CON1<4:2>)
that, when combined, create an SPI sample
clock divisor with a value of four or greater.
Work around
Instead of polling the SPITBF bit to test for an
empty buffer (SPI1STAT<1> = 0), implement a
SPI receive interrupt handler in software and
add to the SPI transmit buffer in this routine.
Alternatively, poll the SPI Receive Full bit,
SPIRBF (SPI1STAT<0>), or the Shift Register
Empty bit, SRMPT (SPI1STAT<7>), to determine
when to service the SPI transmit and transmit
buffers.
Affected Silicon Revisions
When
(FPOR<6:5> = 00), Brown-out Reset events
may result in a device Reset in which both the
BOR and POR bits are set.
This differs from the expected behavior of simply
re-arming the POR circuit to ensure that a
Power-on Reset occurs when V
the POR threshold.
Work around
None.

6. Module: Comparator (I/O Pins)
7. Module: Comparator
Certain I/O pins may not function correctly as
digital inputs or outputs after specific comparator
outputs have been enabled with the COE bit
(CMxCON<14> = 1). These are:
•
•
This condition may continue, even after the com-
parator in question has been disabled using the
corresponding CON bit (CMxCON<15> = 0).
Work around
In addition to clearing the CON bit, also clear the
COE bit.
Affected Silicon Revisions
When a comparator is programmed to trig-
ger
(CMxCON<7:6> = 10 or 01), setting the CPOL bit
(CMxCON<13> = 1) may cause the comparator to
flag the opposite edge-detect event (e.g., a
high-to-low edge instead of the programmed
low-to-high).
Work around
Leave CPOL = 0. In addition, use the opposite
setting of CMxCON<7:6> to achieve the correct
response (e.g., use ‘10’ for ‘01’).
