TC0R AUTO-LOAD REGISTER
TC0R is an 8-bit register for the TC0 auto-reload function. TC0R’s value applies to TC0OUT and PWM0OUT functions..
Under TC0OUT application, users must enable and set the TC0R register. The main purpose of TC0R is as following.
ꢂ
ꢂ
Store the auto-reload value and set into TC0C when the TC0C overflow. (ALOAD0 = 1).
Store the duty value of PWM0OUT function.
TC0R initial value = xxxx xxxx

The equation of TC0R initial value is like TC0C as following.
TC0R initial value = 256 - (TC0 interrupt interval time * input clock)
Note: The TC0R is write-only register can’t be process by INCMS, DECMS instructions.
