Description
Event counter clock input pin, timer output and PWM signal output
pin for 8-bit timer 0 to 3. To use this pin as event clock input, con-
figure it as input by P0DIR, P6DIR and PADIR register. In the input
mode, pull-up resistor can be selected in P0PLU, P6PLU, and
PAPLU registers. For timer output, PWM signal output, select the
special function pin in P0OMD1, P0OMD2, P6OMD and PAOMD
registers, and set to the output mode in P0DIR, P6DIR 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
5. The driving frequency can be set in DLYCTR register. In order to
select Buzzer output, select the special function pin in P5OMD reg-
ister, and set P5DIR 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 timer7and 8. To use this pin as event clock input, con-
figure it as input with P0DIR and PADIR registers. In the input
mode, pull-up resistor can be selected by P0PLU and PAPLU reg-
isters. For timer output, PWM signal output, select the special
function pin in P0OMD1 and PAOMD registers, and set to the out-
put mode in P0DIR and PADIR registers. 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 val-
ues of V_REF+ = V_DD5 is used.
Analog input pins for 12-channel, 10-bit A/D converter. Select the
analog input by PAIMD, PBIMD 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.
Input pins for KEY interrupt based on OR condition result of pin
inputs. These can be set to key input pins by 1-bit with KEY inter-
rupt control register (KEYT3_1IMD, KEY3_2_IMD). When not used
for KEY input, these pins can be used as normal I/O pins.
