10 / 51 page Philips Semiconductors P89LPC932 8-bit microcontroller with accelerated two-clock 80C51 core Product data Rev. 04 — 06 January 2004 10 of 60 9397 750 12379 © Koninklijke Philips Electronics N.V. 2004. All rights reserved. [1] Input/Output for P1.0-P1.4, P1.6, P1.7. Input for P1.5. P3.0 - P3.1 9, 8 5, 4 I/O Port 3: Port 3 is a 2-bit I/O port with a user-configurable output type. During reset Port 3 latches are configured in the input only mode with the internal pull-up disabled. The operation of Port 3 pins as inputs and outputs depends upon the port configuration selected. Each port pin is configured independently. Refer to Section 8.12.1 “Port configurations” and Table 8 “DC electrical characteristics” for details. All pins have Schmitt triggered inputs. Port 3 also provides various special functions as described below: 9 5 I/O P3.0 — Port 3 bit 0. O XTAL2 — Output from the oscillator amplifier (when a crystal oscillator option is selected via the FLASH configuration. O CLKOUT — CPU clock divided by 2 when enabled via SFR bit (ENCLK - TRIM.6). It can be used if the CPU clock is the internal RC oscillator, watchdog oscillator or external clock input, except when XTAL1/XTAL2 are used to generate clock source for the Real-Time clock/system timer. 8 4 I/O P3.1 — Port 3 bit 1. I XTAL1 — Input to the oscillator circuit and internal clock generator circuits (when selected via the FLASH configuration). It can be a port pin if internal RC oscillator or watchdog oscillator is used as the CPU clock source, and if XTAL1/XTAL2 are not used to generate the clock for the Real-Time clock/system timer. VSS 73 I Ground: 0 V reference. VDD 21 17 I Power Supply: This is the power supply voltage for normal operation as well as Idle and Power-Down modes.
