or outputs. This has only been seen in a few
unique system environments.
A test of a statistically significant sample of pre-
production systems, across the voltage and
current range of the application’s power supply,
should indicate if a system is susceptible to this
issue.
Work around
Before configuring the module for I

Once this is done, use the SSPCON1 and
SSPCON2 registers to configure the proper I
mode as before.

All engineering and production devices.
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 2,
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.

In SPI mode, the SDO output may change after the
inactive clock edge of the bit ‘0’ output. This may
affect some SPI components that read data over

Due to production tolerances, selecting the lowest
setting for Brown-out Detect (BORV1:BORV0 = 11)
or Low-Voltage Reset (LVV = 0000) is not recom-
mended, since it may result in an actual Brown-out
