DESCRIPTION
P0.0 - P0.7.
General purpose I/O Port 0. This port is open-drain and can not 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.
P1.0 - P1.7.
General purpose I/O Port 1.
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.
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.
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.
P3.3
INT1
.
General purpose I/O port pin 3.3. Also serves as the active low External
Interrupt 1.
P3.4 T0.
General purpose I/O port pin 3.4. Also serves as the Timer 0 input.
P3.5 T1.
General purpose I/O port pin 3.5. Also serves as the Timer 1 input.
P3.6
WR
.
General purpose I/O port pin. Also serves as the write strobe for Expanded bus
operation.
P3.7
RD
.
General purpose I/O port pin. Also serves as the read strobe for Expanded bus
operation.
RST -
Active high reset input. A logic 1 applied to this pin will activate a reset state. This
pin is pulled down internally, can be left unconnected if not used. An RC power-on reset
circuit is not needed and is NOT recommended.
