When the MSSP is configured for SPI mode, the
Buffer Full Status bit, BF (SSPSTAT<0>), should
not be polled in software to determine when the
transfer is complete.
Work around
Copy the SSPSTAT register into a variable and
perform the bit test on the variable. In Example 5,
SSPSTAT is copied into the working register
where the bit test is performed.
A second option is to poll the Master Synchronous
Serial Port Interrupt Flag bit, SSPIF (PIR1<3>).
This bit can be polled and will set when the transfer
is complete.

Under specific conditions, the first five bits of a
transmitted identifier may not match the value in
the Transmit Buffer ID register, TXBnSIDH. The
following conditions must exist for the corruption to
occur:
1. A transmit message must be pending.
2. The ECAN module must detect a Start-Of-

The Error Interrupt Flag, ERRIF (PIR3<5>), may
not be able to clear in software after either of the
following counter registers exceeds 127.
• Transmit Error Counter Register TXERRCNT
• Receive Error Counter Register RXERRCNT
Work around
Monitor the EWARN (COMSTAT<0>) bit to deter-
mine if either the TXERRCNT or the RXERRCNT
exceeds 95 and clear the ERRIF flag before either
counter reaches 127.
Date Codes that pertain to this issue:
All engineering and production devices.
Following an error on the bus, the ECAN module is
unable to switch from Listen Only mode directly to
Configuration mode.
Work around
Use the REQOP (CANCON<7:5>) bits to select
Normal mode as an intermediate step when
switching from Listen Only mode to Configuration
mode.
