Gate Source
Timer1 Gate Toggle mode provides unexpected
results when Timer0 overflow is selected as the
Timer1 gate source. We do not recommend using
Timer0 overflow as the Timer1 gate source while in
Timer1 Gate Toggle mode or when Toggle mode is
used in conjunction with Timer1 Gate Single-Pulse
mode.
Work around
None.
Affected Silicon Revisions
When Timer1 Gate Toggle mode is enabled, it is
possible to measure the full-cycle length of a
Timer1 gate signal. To perform this function, the
Timer1 gate source is routed through a flip-flop
that changes state on every incrementing edge of
the gate signal. Timer1 Gate Toggle mode is
enabled by setting the T1GTM bit of the T1GCON
register. When working properly, clearing either
the T1GTM bit or the TMR1ON bit would also clear
the output value of this flip-flop, and hold it clear.
This is done in order to control which edge is being
measured. The issue that exists is that clearing the
TMR1ON bit does not clear the output value of the
flip-flop and hold it clear.
Work around
Clear the T1GTM bit in the T1GCON register to
clear and hold clear the output value of the flip-
flop.
