Description
Event counter clock input pin, timer output and PWM signal output
pin for 8-bit timer 0 to 2.
To use this pin as event clock input, configure it as input by P0DIR
register, P3DIR register, P4DIR register and PADIR register. In the
input mode, pull-up resistor can be selected in P0PLU, P3PLU,
P4PLU and PAPLU registers.
For timer output, PWM signal output, select the special function pin
in P0OMD, P3OMD, P4OMD and PAOMD registers, and set to the
output mode in P0DIR, P3DIR, P4DIR and PADIR registers.
These can be used as normal I/O pins when Timer I/O pin is not
used.
Piezoelectric buzzer driving pin. Buzzer output is available to Port 3.
The driving frequency can be set in DLYCTR register.
In order to select Buzzer output to Port 3, select the special function
pin in P3OMD register, and set P3DIR register to the output mode.
At the same time, select Buzzer output in oscillation stabilization wait
control register (DLYCTR).
These can be used as normal I/O pins when Buzzer output is not
used.
Event counter clock input pin, timer output and PWM signal output
pin for 16-bit timer7 and 9.
To use this pin as event clock input, configure it as input with P0DIR,
P4DIR and PADIR registers. In the input mode, pull-up resistor can
be selected by P0PLU, P4PLU and PAPLU registers.
For timer output, PWM signal output, select the special function pin
in P0OMD, P4OMD and PAOMD registers, and set to the output
mode in P0DIR, P4DIR and PADIR registers.
These can be used as normal I/O pins when not used as timer I/O
pins.
PWM signal output pin for 16-bit timer 9.
Select the special function pin in P0OMD register, and set to the out-
put mode in P0DIR register.
These can be used as normal I/O pins when not used as timer I/O
pins.
Reference power supply pin for A/D converter.
Normally, the values of VREF+ = VDD5 is used.
Analog input pins for 12-channel, 10-bit A/D converter.
Select the analog input by PAIMD register.
When not used for analog input, these pins can be used as normal
input pins.
External interrupt input pins.
Select the external interrupt input enable by IRQCNT register.
The valid edge for IRQ0 to 4 can be selected with IRQnICR register.
IRQ2 to 4 can be set at both edges at pin voltage level.
When not used for interrupts, these can be used as normal input
pins.
