9.12 I/O ports
The P89LPC916 and P89LPC917 devices have three I/O ports: Port 0, Port 1, and
Port 2. The exact number of I/O pins available depends on the clock and reset options
chosen, as shown in
Table 10
.
[1]
Required for operation above 12 MHz.
The P89LPC915 has 2I/O ports: Port 0, and Port 1. The exact number of I/O pins
available depends on the reset option chosen, as shown in
Table 11
.
[1]
Required for operation above 12 MHz.
9.12.1
Port configurations
Except as listed below, every I/O pin on the P89LPC915/916/917 may be configured
by software to one of four types on a bit-by-bit basis. These are: quasi-bidirectional
(standard 80C51 port outputs), push-pull, open drain, and input-only. Two
configuration registers for each port select the output type for each port pin.
P1.5/RST can only be an input and cannot be configured.
SCL/T0/P1.2 and SDA/INTO/P1.3 may only be configured to be either input-only or
open drain.
9.12.2
Quasi-bidirectional output configuration
Quasi-bidirectional output type can be used as both an input and output without the
need to reconfigure the port. This is possible because when the port outputs a logic
HIGH, it is weakly driven, allowing an external device to pull the pin LOW. When the
