The corresponding PWM-channel is disabled. P1.i functions
as normal bidirectional I/O-port.
He corresponding PWM-channel is enabled. E0...E5 are
channels with 8-bit resolution, while E6 and E7 are channels
with 14-bit resolution.

This bits define the high time of the output. If all bits are 0, the
high time is 0 internal clocks. If all bits are 1, the high time is
63 internal clocks.
If this bit is set, every second PWM-Cycle is stretched by one
internal clock, regardless of the settings of Bit7...Bit2.
If this bit is set, every fourth PWM-Cycle is stretched by one
internal clock, regardless of the settings of Bit7...Bit2.
