• Bits 5,4 - COM1B1S, COM1B0S: Comparator B Output Mode, Bits 1 and 0
These bits are the shadow bits of the COM1A1 and COM1A0 bits that are described in the sec-
tion
• Bits 3,2 - COM1D1, COM1D0: Comparator D Output Mode, Bits 1 and 0
These bits control the behaviour of the Waveform Output (OCW1D) and the connection of the
Output Compare pin (OC1D). If one or both of the COM1D1:0 bits are set, the OC1D output
overrides the normal port functionality of the I/O pin it is connected to. The complementary
OC1D output is connected only in PWM modes when the COM1D1:0 bits are set to “01”. Note
that the Data Direction Register (DDR) bit corresponding to the OC1D pin must be set in order to
enable the output driver.
The function of the COM1D1:0 bits depends on the PWM1D and WGM10 bit settings.
