Timer Counter Registers (TIMH:TIM):
The TIM register holds the low 16 bits of the current 32-bit
count of the timer. The TIMH register holds the high 16 bits of the current 32-bit count of the timer.
The TIMH:TIM decrements by one every (TDDRH:TDDR+1) clock cycles, where TDDRH:TDDR
is the timer prescale divide-down value. When the TIMH:TIM decrements to zero, the TIMH:TIM
register is reloaded with the period value contained in the PRDH:PRD registers. The timer interrupt
(TINT) signal is generated.

Timer Period Registers (PRDH:PRD):
The PRD register holds the low 16 bits of the 32-bit period.
The PRDH register holds the high 16 bits of the 32-bit period. When the TIMH:TIM decrements to
zero, the TIMH:TIM register is reloaded with the period value contained in the PRDH:PRD
registers, at the start of the next timer input clock cycle (the output of the prescaler). The
PRDH:PRD contents are also loaded into the TIMH:TIM when you set the timer reload bit (TRB)
in the Timer Control Register (TCR).
