Port 1
(
P1.0 to P1.7).
8-bit bidirectional I/O port with internal pull-ups;
INT2 to INT8
:
external interrupt inputs;
T2:
Timer T2 I/O;
T2EX:
Timer 2 external input;
SCL:
I
2
C-bus interface clock;
SDA:
I
2
C-bus interface data.
Port 1 pins that have logic 1s written to them are pulled HIGH by the internal pull-ups,
and in that state can be used as inputs (note P1.6 and P1.7 are open-drain only).
As inputs, Port 1 pins that are externally pulled LOW will source current
(I
IL
, see Chapter 25) due to the internal pull-ups.
Port 3 (P3.0 to P3.7).
8-bit bidirectional I/O port with internal pull-ups;
RXD:
serial
port receiver data input (asynchronous);
TXD:
serial port transmitter data output
(asynchronous);
INT0:
external interrupt 0;
INT1:
external interrupt 1;
T0
: Timer 0 external input;
T1:
Timer 1 external input.
Port 3 pins that have logic 1s written to them are pulled HIGH by the internal pull-ups,
and in that state can be used as inputs. As inputs, Port 3 pins that are externally pulled
LOW will source current (I
IL
, see Chapter 25) due to the internal pull-ups.
Port 4 (P4.0 to P4.7).
8-bit bidirectional I/O port;
RAMCE
chip enable for external
RAM.
Port 4 pins that have logic 1s written to them are pulled HIGH by the internal pull-ups,
and in that state can be used as inputs. As inputs, Port 4 pins that are externally pulled
LOW will source current (I
IL
, see Chapter 25) due to the internal pull-ups.
