The PA0 and PA1 are pin-shared with BZ and BZ signal,
respectively. If the BZ/BZ option is selected, the output
signal in output mode of PA0/PA1 will be the buzzer sig-
nal generated by multi-function timer. The input mode
always remain in its original function. Once the BZ/BZ
option is selected, the buzzer output signal are con-
trolled by the PA0/PA1 data register only.
The I/O function of PA0/PA1 are shown below.

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). Writing 1 to
PD0~PD3 data register will enable the PWM output
function and writing 0 will force the PD0~PD3 to re-
main at 0 . The I/O functions of PD0/PD1/PD2/PD3 are
as shown.
