MOTOR CONTROLLER (Cont’d)

If the 13-bit Compare register value is greater than

the extended Compare 0 Register (the 13th bit is

set to ‘0’), the corresponding PWM output signal is

held at ‘1’.

If the 13-bit Compare register value is 0, the corre-

sponding PWM output signal is held at ‘0’.

Figure 119 shows some center-aligned PWM

waveforms in an example where the Compare 0

register value = 8.
