Input Register 0 and Input Register 1 reflect the incoming logic levels of the I/O pins, regardless of whether the pin is defined
as an input or an output. These registers are read only ports. Writes to the input registers will be acknowledged but will have
no effect.

The Frequency Prescaler 0 and Frequency Prescaler 1
registers (PSC0, PSC1) are used to program the period of the
pulse width modulated signals BLINK0 and BLINK1
respectively:
T_BLINK0 = (PSC0 + 1) / 44;
T_BLINK1 = (PSC1 + 1) / 44
Every LED driver output can be programmed to one of
four states, LED OFF, LED ON, LED blinks at BLINK0 rate
and LED blinks at BLINK1 rate using the LED Selector
Registers (Table 10).

After writing to the PWM0/1 register an 8 ? bit internal
counter starts to count from 0 to 255. The outputs are low (LED
on) when the counter value is less than the value programmed
into PWM register. The LED is off when the counter value is
