P89LPC932A1
8-bit microcontroller with accelerated two-clock 80C51 core
[1]
Required for operation above 12 MHz.
7.13.1 Port congurations
All but three I/O port pins on the P89LPC932A1 may be congured 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 conguration registers for each port
select the output type for each port pin.
1. P1.5 (RST) can only be an input and cannot be congured.
2. P1.2 (SCL/T0) and P1.3 (SDA/INT0) may only be congured to be either input-only or
open-drain.
7.13.1.1
Quasi-bidirectional output conguration
Quasi-bidirectional output type can be used as both an input and output without the need
to recongure 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 pin is driven
LOW, it is driven strongly and able to sink a fairly large current. These features are
somewhat similar to an open-drain output except that there are three pull-up transistors in
the quasi-bidirectional output that serve different purposes.
The P89LPC932A1 is a 3 V device, but the pins are 5 V-tolerant. In quasi-bidirectional
mode, if a user applies 5 V on the pin, there will be a current owing from the pin to VDD,
causing extra power consumption. Therefore, applying 5 V in quasi-bidirectional mode is
discouraged.
A quasi-bidirectional port pin has a Schmitt trigger input that also has a glitch suppression
circuit.
7.13.1.2
Open-drain output conguration
The open-drain output conguration turns off all pull-ups and only drives the pull-down
transistor of the port driver when the port latch contains a logic 0. To be used as a logic
output, a port congured in this manner must have an external pull-up, typically a resistor
tied to VDD.
An open-drain port pin has a Schmitt trigger input that also has a glitch suppression
circuit.
7.13.1.3
Input-only conguration
The input-only port conguration has no output drivers. It is a Schmitt trigger input that
also has a glitch suppression circuit.
