MC68HC11G5
In mode 0, the event counter operates as an 8-bit PWM unit with an 8-bit phase shifter. If mode 0
is selected (EVMDB = 0, EVMDA = 0), then the elements of the event counter are configured as
shown in Figure 11-2.
11.2.1 Operation of PWM and PA Unit in Mode 0
The period of the modulated output is controlled by an external signal applied to the EVI2 pin. The
active edge of this input signal is selected via the INPUT2 selector. This input signal clears EVCNT2
in the PA unit and starts the 8-bit phase shift sequence.
