The PB can also be used as A/D converter inputs. The
A/D function will be described later. There is a PWM
function shared with PD0/PD1/PD2/PD3. If the PWM
function is enabled, the PWM0/PWM1/PWM2/PWM3
signal will appear on PD0/PD1/PD2/PD3 (if
PD0/PD1/PD2/PD3 is operating in output mode). Writ-
ing 1 to PD0~PD3 data register will enable the PWM
outputfunctionandwriting 0 willforcethePD0~PD3to
remain at 0 . The I/O functions of PD0/PD1/PD2/PD3
are as shown.

PWM
The microcontroller provides 4 channels (6+2)/(7+1)
(dependent on options) bits PWM output shared with
PD0/PD1/PD2/PD3.ThePWMchannelshavetheirdata
registers denoted as PWM0 (1AH), PWM1 (1BH),
PWM2 (1CH) and PWM3 (1DH). The frequency source
of the PWM counter comes from f
SYS
. The PWM regis-
ters are four 8-bit registers. The waveforms of PWM out-
puts are as shown. Once the PD0/PD1/PD2/PD3 are
selected as the PWM outputs and the output function of
PD0/PD1/PD2/PD3 are enabled (PDC.0/PDC.1/
PDC.2/PDC.3= 0 ), writing 1 to PD0/PD1/PD2/PD3
