PWM FUNCTION DESCRIPTION

OVERVIEW

PWM function is generated by TC0/TC1 timer counter and output the PWM signal to PWM0OUT pin (P5.4)/
PWM1OUT pin (P5.3). When code option TC0/TC1_Counter= 8-bit, the 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. Table 7-4 listed the low-to-high ratio (duty) of the
PWM0/PWM1 output.

For example, TC0_Counter=8-bit, all PWM outputs remain inactive during the first 256 input clock signals. Then, when
the counter value (TC0C/TC1C) changes from FFH back to 00H, the PWM output is forced to high level. The pulse
width ratio (duty cycle) is defined by the contents of the reference register (TC0R/TC1R) and is programmed in
increments of 1:256. The 8-bit PWM data register TC0R/TC1R is write-only register. Different code option of
TC0_Counter/TC1_Counter will cause different PWM Duty, so user can generate different PWM output by selection
different TC0_Counter/TC1_Counter.

PWM output can be held at low level by continuously loading the reference register with 00H. Under PWM operating, to
change the PWM’s duty cycle is to modify the TC0R/TC1R.
