2 GENERAL DESCRIPTION
The P8xCL883/P8xCL884 are manufactured in an
advanced CMOS technology. The P8xCL883 is based on
single-chip technology and the P8xCL884 is based on
MCM (Multi-Chip-Module) technology as the EEPROM is
integrated on a separate chip.
The P8xCL883/P8xCL884 are 8-bit microcontrollers
especially suited for low cost analog cordless telephone
applications (CT0, CT1, CT1+ standards). For this
purpose, features like DTMF, EEPROM, MSK modem and
POR/LVD are integrated on-chip.
The device is optimized for low power consumption.
The P8xCL883/P8xCL884 have two software selectable
features for power reduction: Idle and Power-down modes.
In addition, all derivative blocks can switch off their clock if
they are inactive.
The instruction set of the P8xCL883/P8xCL884 is based
on that of the 80C51. The P8xCL883/P8xCL884 also
function as an arithmetic processor having facilities for
both binary and BCD arithmetic plus bit-handling
capabilities. The instruction set consists of over
100 instructions: 49 one-byte, 46 two-byte, and
16 three-byte. Due to the missing port P2, there is no
external data or memory access and the MOVX operations
cannot be used.
This data sheet details the specific properties of the
P8xCL883/P8xCL884; for details of the
P8xCL883/P8xCL884 core and the derivative functions

6.2 I/O facilities
6.2.1 PORTS
The P8xCL883/P8xCL884 have 19 and 18 I/O lines
respectively, treated as 19 and 18 individually addressable
bits or as three parallel 8-bit addressable ports.
The alternative functions are detailed below:
Port 0 Offers no alternative functions.
Port 1 Used for a number of special functions:
• P1.0 to P1.7 provides the inputs for the external
interrupts INT2 to INT9
• P1.2/T2COMP for external activation and
Compare/Auto-reload output function of Timer 2
• P1.4/CLK for the clock output
• P1.6/SCL and P1.7/SDA for the I2C-bus interface
are real open-drain outputs or high-impedance;
no other port configurations are available.
Port 2 Not available.
Port 3 Pins can be configured individually to provide:
• P3.0/RXD/data and P3.1/TXD/clock/MOUT0
which are serial port receiver input and
transmitter output (UART)
• P3.4/T0 as counter input; available only in
P8xCL883.
To enable a Port pin alternative function, the Port bit latch
in its SFR must contain a logic 1.
ADDRESS

P8xCL883; P8xCL884
Each port consists of a latch (Special Function Registers
P0 to P3), an output driver and input buffer. All ports have
internal pull-ups. Figure 3b shows that the strong
transistor ‘p1’ is turned on for only one oscillator period
after a LOW-to-HIGH transition in the port latch. When on,
it turns on ‘p3’ (a weak pull-up) through the inverter IN1.
This inverter and transistor ‘p3’ form a latch which holds
the logic 1.
Port P1.3 has LED drive capability.
6.2.2 P
I/O port output configurations are determined by the
settings in port configuration SFRs. There are 2 SFRs for
each port: PnCFGA and PnCFGB, where ‘n’ indicates the
specific port number (0 to 3). One bit in each of the 2 SFRs
relates to the output setting for the corresponding port pin,
allowing any combination of the 2 output types to be mixed
on those port pins. For example, the output type of P1.3, is
controlled by the setting of bit 3 in the SFRs P1CFGA and
P1CFGB.
The port pins may be individually configured via SFRs with
one of the following modes (P1.6 and P1.7 can be
open-drain or high-impedance but never have any diodes
against VDD). These modes are also shown in Fig.3.
Mode 0 Open-drain; quasi-bidirectional I/O with
Mode 1 Standard port; quasi-bidirectional I/O with
Mode 2 High-impedance; this mode turns off all output
Mode 3 Push-pull; output with drive capability in both

n-channel open-drain output. Use as an output
requires the connection of an external pull-up
resistor; e.g. Port 0 for external memory
accesses (EA = 0) or access above the built-in
memory boundary. The ESD protection diodes
against VDD and VSS are still present; see Fig.3b.
Except for the I2C-bus pins P1.6 and P1.7, ports
which are configured as open-drain still have a
protection diode to VDD.
pull-up. The strong pull-up ‘p1’ is turned on for
only two oscillator periods after a LOW-to-HIGH
transition in the port latch. After these two
oscillator periods the port is only weakly driven
through ‘p2’ and ‘very weakly’ driven through ‘p3’
(see Fig.3b).
drivers on a port. Thus, the pin will not source or
sink current and may be used as an input-only pin
with no internal drivers for an external device to
overcome (see Fig.3c).

used as outputs (see Fig.3d).

Tables 2 and 3 show the configuration register settings for
the 4 port output types.
The electrical characteristics of each output type can be
