16.11 Register Description
16.11.1
7753F–AVR–01/11
TCCR1A – Timer/Counter1 Control Register A
• Bits 7,6 - COM1A1, COM1A0: Comparator A Output Mode, Bits 1 and 0
These bits control the behavior of the Waveform Output (OCW1A) and the connection of the
Output Compare pin (OC1A). If one or both of the COM1A1:0 bits are set, the OC1A output
overrides the normal port functionality of the I/O pin it is connected to. The complementary
OC1B output is connected only in PWM modes when the COM1A1:0 bits are set to “01”. Note
that the Data Direction Register (DDR) bit corresponding to the OC1A and OC1A pins must be
set in order to enable the output driver.
The function of the COM1A1:0 bits depends on the PWM1A, WGM10 and WGM11 bit settings.
