2001 Microchip Technology Inc.
The Timer1 value may unexpectedly increment if
either the TMR1H or the TMR1L register is written.
If Timer1 is ON, then turned OFF, performing any
write instruction with TMR1H as the destination
may cause TMR1L to increment.
If Timer1 is ON, then turned OFF when
TMR1H:TMR1L = xx:FF, performing any write
instruction with TMR1L as the destination may
cause TMR1H to increment.
Work around
To preserve Timer1 register values:
a) Read Timer1 register values into “shadow”
b) Perform any write instruction(s) on the
c) Write the shadow register values back into
