Silicon Errata Issues
1. Module: Reset
2. Module: MSSP (I
 2010 Microchip Technology Inc.
Note:
When a Brown-out Reset (BOR) occurs and the
BOR bit is reset, the Power-on Reset (POR) bit
also may be reset. The resulting state matches
that of the RCON register following a Power-on
Reset event.
Consequently, an application may not be able to
detect whether a BOR or POR event has occurred.
Work around
None.
Affected Silicon Revisions

the Serial Receive/Transmit Buffer register
(SSPBUF) is not read within a window after the
SSPIF interrupt (PIR<3>) has occurred.
Work around
The issue can be resolved in either of these ways:
• Prior to the I
• Each time the SSPIF bit is set, read the

When in I
clock stretching, the first clock pulse after the
slave releases the SCL line may be narrower
than the configured clock width. This may result
in the slave missing the first clock in the next
transmission/reception.
Work around
The clock pulse will be the normal width if the slave
does not perform clock stretching.
Affected Silicon Revisions
In rare situations, when interrupts are enabled,
unexpected results may occur if:
• The EUSART is disabled (the SPEN bit,
• The EUSART is re-enabled (RCSTA<7> = 1)
• A two-cycle instruction is executed
