DESCRIPTION
39–32
P0.0–P0.7. General-purpose I/O Port 0. This port is open-drain and cannot drive a logic 1. It
requires external pullups. Port 0 is also the multiplexed Expanded Address/Data bus. When
used in this mode, it does not require pullups.
1–8
P1.0–P1.7. General-purpose I/O Port 1.
21–28
P2.0–P2.7. General-purpose I/O Port 2. Also serves as the MSB of the Expanded Address
bus.
10
P3.0/RXD. General-purpose I/O port pin 3.0. Also serves as the receive signal for the on-
board UART. This pin should NOT be connected directly to a PC COM port.
11
P3.1/TXD. General-purpose I/O port pin 3.1. Also serves as the transmit signal for the on-
board UART. This pin should NOT be connected directly to a PC COM port.
12
P3.2/ INT0 . General-purpose I/O port pin 3.2. Also serves as the active low External
Interrupt 0.
13
P3.3/ INT1 . General-purpose I/O port pin 3.3. Also serves as the active low External
Interrupt 1.
14
P3.4/T0. General-purpose I/O port pin 3.4. Also serves as the Timer 0 input.
