Timer Reset Bit
Set this bit will reset the timer, prescale and also force CEN to 0.
0 = No effect
1 = Reset Timer’s prescale counter, internal 24-bit up-timer and CEN bit
Timer Active Status Bit (Read only)
This bit indicates the status of timer.
0 = Timer is not active
1 = Timer is in active
Reserved
Data Load Enable
When TDR_EN is set, TDR (Timer Data Register) will be updated continuously with
the 24-bit up-timer value.
1 = Timer Data Register update enable
0 = Timer Data Register update disable
Reserved
Pre-scale Counter
Clock input is divided by PRESCALE+1 before it is fed to the timer. If PRESCALE =0,
then there is no scaling.

Timer Operating Mode
The timer is operating in the one-shot mode. The associated
interrupt signal is generated once (if IE is enabled) and CEN is
automatically cleared by hardware.
The timer is operating in the periodic mode. The associated
interrupt signal is generated periodically (if IE is enabled).
The timer is operating in the toggle mode. The interrupt signal is
generated periodically (if IE is enabled). And the associated
signal (tout) is changing back and forth with 50% duty cycle.
