The Timer1 value may unexpectedly increment if
either the TMR1H, or the TMR1L register is writ-
ten. If Timer1 is ON and then turned OFF, perform-
ing any write instruction with TMR1H as the
destination, may cause TMR1L to increment.

Work around
To preserve Timer1 register values:
a) Read Timer1 register values into “shadow”
b) Perform any write instruction(s) on the
