When performing back-to-back transmission in 9-bit
mode (TX9D bit in the TXSTA register is set), the
second byte may be corrupted if it is written into
TXREG immediately after the TMRT bit is set.
Work around
Execute a software delay, at least one-half the
transmission’s bit time, after TMRT is set and prior
to writing subsequent bytes into TXREG.
Date Codes that pertain to this issue:
All engineering and production devices.
When Timer1 or Timer3 is configured for external
clock source, and the CCPxCON register is
configured with 0x0B (Compare mode, trigger
special event), the timer is not reset on a Special
Event Trigger.
Work around
Modify firmware to reset the Timer1/Timer3
registers upon detection of the compare match
condition — TMRxL and TMRxH.
Date Codes that pertain to this issue:
All engineering and production devices.
21. Module: Timer1/Timer3
22. Module: Timer1/Timer3
When Timer1 or Timer3 is in External Clock
Synchronized mode and the external clock period
is between 1 and 2 T
be skipped.
Work around
Avoid using an external clock with a period (1/
frequency) between 1 and 2 T
Date Codes that pertain to this issue:
All engineering and production devices.
When Timer1/Timer3 is operating in 16-bit mode
and the prescale setting is not 1:1, a write to the
TMR1H/TMR3H Buffer registers may lengthen the
duration of the period between the increments of
the timer for the period in which TMR1H/TMR3H
was written.
Work around
Two work arounds are available: 1) Stop Timer1/
Timer3
registers; 2) Write TMR1L/TMR3L immediately
after writing TMR1H/TMR3H.
Date Codes that pertain to this issue:
All engineering and production devices.
