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, 3, 5, 7, 9,
11, 13, 15
P1.0 - P1.7. General purpose I/O Port 1.
40, 38, 36,
34, 32, 30,
28, 26
P2.0 - P2.7. General purpose I/O Port 2. Also serves as the MSB of the Expanded
Address bus.
19
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.
21
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.
23
P3.2 INT0 . General purpose I/O port pin 3.2. Also serves as the active low External
Interrupt 0. This pin is also connected to the INTP output of the DS1283 Real Time
Clock.
25
P3.3 INT1 . General purpose I/O port pin 3.3. Also serves as the active low External
Interrupt 1.
27
P3.4 T0. General purpose I/O port pin 3.4. Also serves as the Timer 0 input.
29
P3.5 T1. General purpose I/O port pin 3.5. Also serves as the Timer 1 input.
31
P3.6 WR . General purpose I/O port pin. Also serves as the write strobe for Expanded
bus operation.
33
P3.7 RD . General purpose I/O port pin. Also serves as the read strobe for Expanded
bus operation.
