PIC16F870/871
6.7
TMR1H and TMR1L registers are not reset to 00h on a
POR, or any other RESET, except by the CCP1 special
event trigger.
T1CON register is reset to 00h on a Power-on Reset,
or a Brown-out Reset, which shuts off the timer and
leaves a 1:1 prescale. In all other RESETS, the register
is unaffected.
