8.4 PWM FUNCTION DESCRIPTION

8.4.1 OVERVIEW

PWM function is generated by TC0/TC1 timer counter and output the PWM signal to PWM0OUT pin (P5.4)/
PWM1OUT pin (P5.3). The 8-bit counter counts modulus 256, from 0-255, inclusive. The value of the 8-bit counter is
compared to the contents of the reference register TC0R/TC1R. When the reference register value (TC0R/TC1R) is
equal to the counter value TC0C/TC1C, the PWM output goes low. When the counter reaches zero, the PWM output is
forced high.

Initial PWM output level is low until the counter value cross boundary (e.g. TC0C changes from FFH back to 00H), the
PWM outputs are forced to high level. The pulse width ratio (duty cycle) is defined by TC0R/TC1R registers and the
overflow boundary is defined by ALOAD0/ALOAD1 and TC0OUT/TC1OUT bits. PWM output can be held at low level
by continuously loading the TC0R/TC1R with 00H. By continuously loading the TC0R with boundary value (e.g. FFH),
you can hold the PWM output to high level, except for the last pulse of the clock source, which sends the output low.

NOTE: If PWM0OUT or TC0OUT is enabled, P5.4 mode will be forced as output mode automatically.

When PWM0OUT or TC0OUT is disabled, P5.4 mode will be defined by P54M bit.
