P0.0-P0.7 I/O Bit-programmable I/O port for Schmitt trigger
input or open-drain output. Port0 can be
individually configured as external interrupt
inputs. Pull-up resistors are assignable by
software.
B 36–29
(30–23) INT2
P1.0-P1.7 I/O Bit-programmable I/O port for Schmitt trigger
input or open-drain output. Pull-up resistors are
assignable by software.
B 28–21
(22–15) –
P2.0-P2.7 I/O Bit-programmable I/O port for Schmitt trigger
input or open-drain output. Port2 can be
individually configured as external interrupt
inputs. Pull-up resistors are assignable by
software.
B 3–10
(41–44, 1–4) INT0
P3.0-P3.3 I/O Bit-programmable I/O port for Schmitt trigger
input, open-drain or push-pull output. P3.3 can
be used to system clock output(CLO) pin.
C 2, 1, 42, 41
(40–37) P3.3/CLO
P4.0-P4.3 I/O Bit-programmable I/O port for Schmitt trigger
input or open-drain output or push-pull output.
Port4 can be individually configured as external
interrupt inputs. In output mode, pull-up resistors
are assignable by software. But in input mode,
pull-up resistors are fixed.
