2.6 PWM

Fig. 2.6.8 PWM0 output

Control procedure: PWM waveform is output to the external by setting relevant registers shown

Figure 2.6.6. This PWM0 output is integrated through the low pass filter and

converted into DC signals for control of the VS tuner.

Figure 2.6.7 shows the control procedure.

2.6.4 Notes on use

q For PWM0 output, “L” level is output first.

q After data is set to the PWM register (low-order) and the PWM register (high-order), PWM waveform

corresponding to new data is output from next repetitive cycle.

PWMH (address 001416)

PWML (address 001516)

Data to be

output

After setting data, PWM waveform

corresponding to the new data is output from

the next repetitive cycle.

PWMCON (address 002616), bit 0

The P87/PWM0/FLD39 pin is set to the PWM

output pin.

PWM0 output data

change

Modified data is output from next

repetitive cycle.
