10001010 (0x8A)
10001100 (0x8C)
10001110 (0x8E)
The least significant two bits for the Pulse Width Modulator count are
stored
These bits are ignored.
PWM output High for single block.
Spread PWM output throughout the cycle
Address = 10001001 (0x89)
Address = 10001011 (0x8B)
Address = 10001101 (0x8D)
Address = 10001111 (0x8F)
The most significant eight bits for the Pulse-Width Modulator count
are stored
With a count of n, the PWM output will be high for n +1 clocks out of
the 1024 clocks of the PWM counter.
