DESCRIPTION

Active LOW reset. A LOW level on this pin for two machine cycles while the

oscillator is running, resets the device. The RST pin is also an output which can be

used to reset other ICs.

Digital MSK modem input.

Digital MSK modem outputs.

Crystal input. Input to the Amplitude Controlled Oscillator. Also the input for an

externally generated clock source.

Crystal output. Output of the Amplitude Controlled Oscillator. To be left

unconnected when an external oscillator clock is used.

Power supply.

Ground.

Port 0. 8-bit bidirectional I/O port. Every port pin can be used as open-drain,

standard port, high-impedance input or push-pull output, according to Section 6.2.

Port 1. 8-bit bidirectional I/O port with alternative functions. Every port pin except

P1.6 and P1.7 (I2C-bus pins) can be used as open-drain, standard port,

high-impedance input or push-pull output, according to Section 6.2. Port P1.3 has

LED drive capability.

Port 1 also serves the alternative functions: INT2 to INT9 interrupts; Timer T2

external inputs T2 and T2EX; Timer T2 compare output T2COMP; external clock

output CLK; I2C-bus clock SCL and data in/outputs SDA.

Port 3. 3 or 2-bit bidirectional I/O port with alternative functions. Every port pin can

be used as open-drain, standard port, high-impedance input or push-pull output,

according to Chapter 6.2.

Port 3 also serves the alternative functions: RXD/data is the serial port receiver

data input (asynchronous) or data I/O (synchronous); TXD/clock is the serial port

transmitter data output (asynchronous) or clock output (synchronous) or digital

MSK modem output MOUT0; T0 is an external input for Timer 0.

P3.4/T0 is only available on the P8xCL883.

DTMF output; TONE is only available on the P8xCL884.

PORENABLE. Power-on reset circuit enable. If PORENABLE = 1, the internal

Power-on reset circuit is enabled. If external reset circuitry is used, it is

recommended to keep PORENABLE = 0 to reach lowest power consumption. This

pin is also used for the OTP programming voltage VPP.
