Product data sheet
6.3.3 PCS0 - Frequency Prescaler 0
6.3.4 PWM0 - Pulse Width Modulation 0
6.3.5 PCS1 - Frequency Prescaler 1
6.3.6 PWM1 - Pulse Width Modulation 1
PSC0 is used to program the period of the PWM output.
The period of BLINK0 = (PSC0 + 1) / 152.
Table 6.
The PWM0 register determines the duty cycle of BLINK0. The outputs are LOW (LED on)
when the count is less than the value in PWM0 and HIGH (LED off) when it is greater. If
PWM0 is programmed with 00h, then the PWM0 output is always HIGH (LED off).
The duty cycle of BLINK0 = PWM0 / 256.
Table 7.
PSC1 is used to program the period of the PWM output.
The period of BLINK1 = (PSC1 + 1) / 152.
Table 8.
The PWM1 register determines the duty cycle of BLINK1. The outputs are LOW (LED on)
when the count is less than the value in PWM1 and HIGH (LED off) when it is greater. If
PWM1 is programmed with 00h, then the PWM1 output is always HIGH (LED off).
The duty cycle of BLINK1 = PWM1 / 256.
