8 / 51 page Philips Semiconductors P89LPC932 8-bit microcontroller with accelerated two-clock 80C51 core Product data Rev. 04 — 06 January 2004 8 of 60 9397 750 12379 © Koninklijke Philips Electronics N.V. 2004. All rights reserved. P1.0 - P1.7 18, 17, 12, 11, 10, 6, 5, 4 14, 13, 8, 7, 6, 2, 1, 28 I/O, I [1] Port 1: Port 1 is an 8-bit I/O port with a user-configurable output type, except for three pins as noted below. During reset Port 1 latches are configured in the input only mode with the internal pull-up disabled. The operation of the configurable Port 1 pins as inputs and outputs depends upon the port configuration selected. Each of the configurable port pins are programmed independently. Refer to Section 8.12.1 “Port configurations” and Table 8 “DC electrical characteristics” for details. P1.2 - P1.3 are open drain when used as outputs. P1.5 is input only. All pins have Schmitt triggered inputs. Port 1 also provides various special functions as described below: 18 14 I/O P1.0 — Port 1 bit 0. O TXD — Transmitter output for the serial port. 17 13 I/O P1.1 — Port 1 bit 1. I RXD — Receiver input for the serial port. 12 8 I/O P1.2 — Port 1 bit 2 (open-drain when used as output). I/O T0 — Timer/counter 0 external count input or overflow output (open-drain when used as output). I/O SCL — I2C serial clock input/output. 11 7 I/O P1.3 — Port 1 bit 3 (open-drain when used as output). I INT0 — External interrupt 0 input. I/O SDA — I2C serial data input/output. 10 6 I P1.4 — Port 1 bit 4. I INT1 — External interrupt 1 input. 62 I P1.5 — Port 1 bit 5 (input only). I RST — External Reset input during power-on or if selected via UCFG1. When functioning as a reset input, a LOW on this pin resets the microcontroller, causing I/O ports and peripherals to take on their default states, and the processor begins execution at address 0. Also used during a power-on sequence to force In-System Programming mode. 5 1 I/O P1.6 — Port 1 bit 6. O OCB — Output Compare B. 4 28 I/O P1.7 — Port 1 bit 7. O OCC — Output Compare C.
