• Bits 5,4 - COM4B1S, COM4B0S: Comparator B Output Mode, Bits 1 and 0
These bits are the shadow bits of the COM4A1 and COM4A0 bits that are described in the sec-
tion
• Bits 3,2 - COM4D1, COM4D0: Comparator D Output Mode, Bits 1 and 0
These bits control the behavior of the Waveform Output (OCW4D) and the connection of the
Output Compare pin (OC4D). If one or both of the COM4D1:0 bits are set, the OC4D output
overrides the normal port functionality of the I/O pin it is connected to. The complementary
OC4D output is connected only in PWM modes when the COM4D1:0 bits are set to “01”. Note
that the Data Direction Register (DDR) bit corresponding to the OC4D pin must be set in order to
enable the output driver.
The function of the COM4D1:0 bits depends on the PWM4D and WGM40 bit settings.
