Product data sheet
6.2.1 Control register definition
6.3.1 INPUT - Input register
6.3.2 PCS0 - Frequency Prescaler 0
6.3.3 PWM0 - Pulse Width Modulation 0
6.3 Register descriptions
Table 4.
The INPUT register reflects the state of the device pins. Writes to this register will be
acknowledged but will have no effect.
Table 5.
Remark: The default value ‘X’ is determined by the externally applied logic level (normally
logic 1) when used for directly driving LED with pull-up to V
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.
