PWM Compare Registers PWCOMP 6, 7
PWM Extension Registers PWEXT 6, 7
Note: The described operation is independent of the setting of PWCOMP6 or
PWCOMP7.
The stretch operation is interleaved between PWM-Cycles.

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
255 internal clocks.

If this bit is set, every second PWM-Cycle is stretched by one
internal clock.
Bit 6
If this bit is set, every fourth PWM-Cycle is stretched by one
internal clock.
Bit 5
If this bit is set, every eighth PWM-Cycle is stretched by one
internal clock.
Bit 4
If this bit is set, every 16th PWM-Cycle is stretched by one
internal clock.
Bit 3
If this bit is set, every 32th PWM-Cycle is stretched by one
internal clock.
Bit 2
If this bit is set, every 64th PWM-Cycle is stretched by one
internal clock.
Bit 1, Bit 0
This bits have to be set to 0.
