Example 12-2
in
Example 12-2:
Writing a 16-bit value to the 16-bit TMR1 register is straight forward. First the TMR1L register is
cleared to ensure that there are many Timer1 clock/oscillator cycles before there is a rollover into
the TMR1H register. The TMR1H register is then loaded, and finally the TMR1L register is loaded.
Example 12-3
Example 12-3:
; All interrupts are disabled
;
; TMR1L may have rolled over between the read of the high and low bytes.
; Reading the high and low bytes now will read a good value.
;
; Re-enable the Interrupt (if required)
CONTINUE
; All interrupts are disabled
; Re-enable the Interrupt (if required)
