MSM66585/586/587/P587/Q587
Built-in 16 bit PWM and 8 bit A/D Converter, High-speed High-preformance 16 bit
Microcontroller
GENERAL DESCRIPTION
MSM66585/586/587 are high-performance CMOS 16-bit microcontrollers that integrate a 16-
bit CPU, ROM, RAM, 8-bit A/D converter, serial port, timers, and PWM. They also allow ROM
and RAM to be expanded externally.
The MSM66P587 is of OTP (One-Time PROM) version and the MSM66Q587 is of Flash EEPROM
version.

Description
Port 0 is 8 input/output pins. Input or output can be specified for each bit with the
Port 0 Mode Register (P0IO). Pull-up resistors can be specified for each bit with the
Port 0 Pull-Up Register (P0PUP).
These pins also function as time-multiplexed address outputs and data input/output
pins (AD0-AD7) when accessing memory that has been expanded externally
(program or data memory).
After reset (by RES signal input, BRK instruction execution, or op code trap), P0 will
be high-impedance inputs.
Port 1 is 8 input/output pins. Input or output can be specified for each bit with the
Port 1 Mode Register (P1IO). Pull-up resistors can be specified for each bit with the
Port 1 Pull-Up Register (P1PUP).
P1_0-P1_7 also have a secondary function as input/output pins for internal operation.
Their secondary function can be set for each bit with the Port 1 Secondary Function
I/O
Control Register (P1SF). The input/output settings by P1IO will be ignored for pins
that have been set to the secondary function by P1SF.
These pins function as output pins for address A8-A15 when accessing program
memory or data memory that has been expanded externally. When the EA pin is low,
A8-A15 will be output regardless of P1SF settings.
After reset (by RES signal input, BRK instruction execution, or op code trap), P1 will
be high-impedance inputs.
P2_4 and P2_5 also have a secondary function as input/output pins for internal operation.
Their secondary function can be set for each bit with the Port 2 Secondary Function
Control Register (P2SF). The input/output settings of P2IO will be ignored for pins
I/O that have been set to the secondary function by P2SF.
These pins output a previously sethttp://www.DataSheet4U.net/ level when the value of Timer Registers 8 and 9
match a selected counter value.
After reset (by RES signal input, BRK instruction execution, or op code trap), P2 will
be high-impedance inputs.
Port 4 is 8 input/output pins. Input or output can be specified for each bit with the
Port 4 Mode Register (P4IO). Pull-up resistors can be specified for each bit with the
Port 4 Pull-Up Register (P4PUP).
P4_0 also has a secondary function as an input pin for internal operation. Its secondary
I/O
function can be set for the bit with the Port 4 Secondary Function Control Register (P4SF).
The input/output settings by P4IO will be ignored for pins that have been set to the
secondary function by P4SF.
This is the external clock input pin for the counter of a general 8-bit timer.
After reset (by RES signal input, BRK instruction execution, or op code trap), P4 will
be high-impedance inputs.
Port 5 is 2 input/output pins. Input or output can be specified for each bit with the
Port 5 Mode Register (P5IO).
P5_4 and P5_5 also have a secondary function as output pins for internal operation.
Their secondary function can be set for each bit with the Port 5 Secondary Function
Control Register (P5SF). The input/output settings of P5IO will be ignored for pins
that have been set to the secondary function by P5SF.
PSEN (P5_4):
This pin outputs the strobe signal for read operations when external program memory
I/O is accessed. Operation will automatically switch to the secondary function when the
EA pin is low. This pin will be pulled up when both the EA pin and RESET pin are low.
ALE (P5_5):
This pin outputs the strobe for externally latching the lower 8 address bits output from
P0 when external memory is accessed. Operation will automatically switch to the
secondary function when the EA pin is low. This pin will be pulled up when both the
EA pin and RESET pin are low.
After reset (by RES signal input, BRK instruction execution, or op code trap), P5 will
be high-impedance inputs.
