Product data sheet
7.16.1.3 Input-only configuration
7.16.1.4 Push-pull output configuration
7.16.2 Port 0 analog functions
7.16.3 Additional port features
7.17 Power monitoring functions
An open-drain port pin has a Schmitt trigger input that also has a glitch suppression
circuit.
The input-only port configuration has no output drivers. It is a Schmitt trigger input that
also has a glitch suppression circuit.
The push-pull output configuration has the same pull-down structure as both the
open-drain and the quasi-bidirectional output modes, but provides a continuous strong
pull-up when the port latch contains a logic 1. The push-pull mode may be used when
more source current is needed from a port output. A push-pull port pin has a
Schmitt triggered input that also has a glitch suppression circuit. The
P89LPC9331/9341/9351/9361 device has high current source on eight pins in push-pull
mode. See
The P89LPC9331/9341/9351/9361 incorporates two Analog Comparators. In order to give
the best analog function performance and to minimize power consumption, pins that are
being used for analog functions must have the digital outputs and digital inputs disabled.
Digital outputs are disabled by putting the port output into the Input-Only
(high-impedance) mode.
Digital inputs on Port 0 may be disabled through the use of the PT0AD register, bits 1:5.
On any reset, PT0AD[1:5] defaults to logic 0s to enable digital functions.
After power-up, all pins are in Input-Only mode. Please note that this is different from
the LPC76x series of devices.
Every output on the P89LPC9331/9341/9351/9361 has been designed to sink typical LED
drive current. However, there is a maximum total output current for all ports which must
not be exceeded. Please refer to
specifications.
All ports pins that can function as an output have slew rate controlled outputs to limit noise
generated by quickly switching output signals. The slew rate is factory-set to
approximately 10 ns rise and fall times.
The P89LPC9331/9341/9351/9361 incorporates power monitoring functions designed to
prevent incorrect operation during initial power-up and power loss or reduction during
operation. This is accomplished with two hardware functions: Power-on detect and
brownout detect.

After power-up, all I/O pins except P1.5, may be configured by software.
Pin P1.5 is input only. Pins P1.2 and P1.3 are configurable for either input-only or
open-drain.
