When operating in external clock mode (TMR1CS is
set), reading either of the timer 1 registers (TMR1H
or TMR1L) may cause the timer not to increment as
expected. This occurs for both synchronous and
asynchronous inputs.
The scenarios which display this are:
• When a read operation of the TMR1H register
• When a read operation of the TMR1L register
Work Around
Do not read either the TMR1H or the TMR1L regis-
ters when operating in external clock mode
(TMR1CS is set). If the application needs to read the
16-bit counter, evaluate if this function can be moved
to the TMR0 or one of the other timer resources on
the device.
occurs, the TMR1L register may not increment.
occurs, the TMR1H register may not increment.
This improper operation is only an issue when
the TMR1L register increments from FFh to 00h
(FFh
