Preliminary data sheet Rev. 01 — 16 April 2009 10 of 74 NXP Semiconductors P89LPC9201/9211/922A1/9241/9251 8-bit microcontroller with 8-bit ADC P0.6/CMP1/KBI6 14 I/O P0.6 — Port 0 bit 6. High current source. O CMP1 — Comparator 1 output. I KBI6 — Keyboard input 6. P0.7/T1/KBI7 13 I/O P0.7 — Port 0 bit 7. High current source. I/O T1 — Timer/counter 1 external count input or overflow output. I KBI7 — Keyboard input 7. P1.0 to P1.7 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 7.16.1 “Port configurations” and Table 12 “Static characteristics” for details. P1.2 to P1.3 are open drain when used as outputs. P1.5 is input only. All pins have Schmitt trigger inputs. Port 1 also provides various special functions as described below: P1.0/TXD 12 I/O P1.0 — Port 1 bit 0. O TXD — Transmitter output for serial port. P1.1/RXD 11 I/O P1.1 — Port 1 bit 1. I RXD — Receiver input for serial port. P1.2/T0/SCL 10 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-bus serial clock input/output. P1.3/INT0/SDA 9 I/O P1.3 — Port 1 bit 3 (open-drain when used as output). I INT0 — External interrupt 0 input. I/O SDA — I2C-bus serial data input/output. P1.4/INT1 8 I/O P1.4 — Port 1 bit 4. High current source. I INT1 — External interrupt 1 input. P1.5/RST 4 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 ISP mode. P1.6 3 I/O P1.6 — Port 1 bit 6. High current source. P1.7 2 I/O P1.7 — Port 1 bit 7. High current source. P3.0 to P3.1 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 7.16.1 “Port configurations” and Table 12 “Static characteristics” for details. All pins have Schmitt trigger inputs. Port 3 also provides various special functions as described below: Table 3. Pin description …continued Symbol Pin Type Description TSSOP20, DIP20 |
