MOTOR CONTROLLER (Cont’d)
■
In this operating mode, the PWM Counter counts
up to the value loaded in the 12-bit Compare Reg-
ister. Then the PWM Counter is cleared and it re-
starts counting up.
The PWM signals are set to ‘0’ when the PWM
Counter reaches, in up-counting, the correspond-
ing 13-bit Compare register value and they are set
to ‘1’ when the PWM Counter is cleared.

If the 13-bit Compare register value is greater than
the extended Compare 0 register (the 13
set to ‘0’), the corresponding PWM output signal is
held at ‘1’.
If the 13-bit Compare register value = 0, the corre-
sponding PWM output signal is held at ‘0’.
