 2010 Microchip Technology Inc.
SPI operating in Enhanced Buffer mode
(SPIBEN = 1) may set the interrupt flag, SPIxIF,
before the last bit has been transmitted from the
shift register. This issue only affects one of the
eight Interrupt modes, SISEL<2:0> = 101,
which generates an interrupt when the last bit
has shifted out of the shift register, indicating the
transfer is complete. All other Interrupt modes in
Enhanced Buffer mode work as described in the
product data sheet.
Work around
Multiple work arounds are available. Select
another Buffer Interrupt mode using the
SISEL<2:0> bits in the SPIxSTAT register. A
comparable mode is to generate an interrupt
when the FIFO is empty, SISEL<2:0> = 110.
Another option is to monitor the SRMPT bit
(SPIxSTAT<7>) to determine when the shift
register is empty.
Affected Silicon Revisions
When
(UxMODE<12> = 1), the operation of the
RXINV bit (UxMODE<4>) is the opposite of its
description in the device data sheet (DS39881);
that is, setting the bit configures the module for
a logic high Idle state, and clearing the bit
configures the module for a logic low Idle state.
Using the bit as described in the data sheet may
result in reception errors.
Work around
Invert the state of the RXINV bit. If the Idle state of
the received signal is logic high, set RXINV = 1. If
the Idle state of the received signal is logic low,
clear RXINV.

45. Module: Core
46. Module: SPI (Master Mode)
Operations that immediately follow any manipula-
tions of the DOZE<2:0> or DOZEN bits
(CLKDIV<14:11>) may not execute properly. In
particular, for instructions that operate on an
SFR, data may not be read properly. Also, bits
automatically cleared in hardware may not be
cleared if the operation occurs during this interval.
Work around
Always insert a NOP instruction before and after
either of the following:

Affected Silicon Revisions
When operating in Enhanced Buffer Master mode,
the module may transmit two bytes or two words of
data with a value of 0h, immediately upon the
microcontroller waking up from Sleep mode. At the
same time, the module “receives” two words or two
bytes of data, also with the value of 0h.
The transmission of null data occurs even if the
Transmit Buffer registers are empty prior to the
microcontroller
received null data requires that the receive buffer
be read twice to clear the “received” data.
This behavior has not been observed when the
module is operating in any other mode.
Work around
When operating in Enhanced Buffer Master mode,
disable the module (SPIEN = 0) before entering
Sleep mode.
