Manual Reload Mode:
- Timer 0 increments until the counter value becomes equal to or greater than VALUE.
- AUX_TIMER0_EV pulses high for 1 AUX clock period when the counter value is equal to or greater than VALUE.

Note: When VALUE is 0, Timer 0 counts to 1. AUX_TIMER0_EV pulses high for 1 AUX clock period.

Continuous Reload Mode:
- Timer 0 increments until the counter value becomes equal to or greater than ( VALUE - 1), then restarts from 0.
- AUX_TIMER0_EV pulses high for 1 AUX clock period when the counter value is 0, except for when you enable the timer.

Note: When VALUE is less than 2, Timer 0 counter value remains 0. AUX_TIMER0_EV goes high and remains high 1 AUX clock period after you enable the timer.
