TC1R AUTO-LOAD REGISTER
TC1R is an 8-bit register for the TC1 auto-reload function. TC1R’s value applies to TC1OUT and PWM1OUT functions.
Under TC1OUT application, users must enable and set the TC1R register. The main purpose of TC1R is as following.
ꢂ
ꢂ
Store the auto-reload value and set into TC1C when the TC1C overflow. (ALOAD1 = 1).
Store the duty value of PWM1OUT function.
TC1R initial value = xxxx xxxx

The equation of TC1R initial value is like TC1C as following.
TC1R initial value = 256 - (TC1 interrupt interval time * input clock)
Note: The TC1R is write-only register can’t be process by INCMS, DECMS instructions.
