SZF2002

I/O Ports

P1.0/INT2/T2

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:

I2C-bus interface clock; SDA: I2C-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

(IIL, see Chapter 25) due to the internal pull-ups.

P1.1/INT3/T2EX

P1.2/INT4

P1.3/INT5

P1.4/INT6

P1.5/INT7

P1.6/INT8/SCL

P1.7/SDA

P3.0/RXD

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 (IIL, see Chapter 25) due to the internal pull-ups.

P3.1/TXD

P3.2/INT0

P3.3/INT1

P3.4/T0

P3.5/T1

P3.6

P3.7

P4.0/RAMCE

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 (IIL, see Chapter 25) due to the internal pull-ups.
