I/O
Port 1:
Port 1 is a 3-bit bidirectional I/O port with internal pull-ups on P1.0 and P1.1. Port 1 pins that
have 1s written to them can be used as inputs. As inputs, port 1 pins that are externally pulled low will
source current because of the internal pull-ups (P1.0, P1.1). (See DC Electrical Characteristics: I
IL
).
Port 1 also serves the special function features listed below (Note: P1.0 does
not
have the strong
pullup that is on for 2 oscillator periods.):
INT0 (P1.0):
External interrupt 0.
CEX (P1.1):
PCA clock output.

I/O
Port 3:
Port 3 is an 8-bit bidirectional I/O port with internal pull-ups. Port 3 pins that have 1s written to
them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 3 pins that are
externally being pulled low will source current because of the pull-ups. (See DC Electrical
Characteristics: I
IL
). (Note: P3.5 does
not
have the strong pullup that is on for 2 oscillator periods.)
Port 3 also serves the special function as listed below:
ECI (P3.6):
External PCA clock input.
RxD/T0 (P3.4):
Serial port receiver data input.
Timer 0 external clock input.
INT1:
External interrupt 1.
TxD/T1 (P3.5):
Serial port transmitter data.
Timer 1 external clock input.
