Resets I/O Ports, PLD macrocells and some of the Configuration Registers. Must be Low
at Power-up.
These pins make up Port A. These port pins are configurable and can have the following
functions:
MCU I/O – write to or read from a standard output or input port.
CPLD macrocell (McellAB0-7) outputs.
Inputs to the PLDs.
Latched address outputs (see Table 6).
Address inputs. For example, PA0-3 could be used for A0-A3 when using an 80C51XA in
burst mode.
As the data bus inputs D0-D7 for non-multiplexed address/data bus MCUs.
D0/A16-D3/A19 in M37702M2 mode.
Peripheral I/O mode.
Note: PA0-PA3 can only output CMOS signals with an option for high slew rate. However,
PA4-PA7 can be configured as CMOS or Open Drain Outputs.
These pins make up Port B. These port pins are configurable and can have the following
functions:
MCU I/O – write to or read from a standard output or input port.
CPLD macrocell (McellAB0-7 or McellBC0-7) outputs.
Inputs to the PLDs.
Latched address outputs (see Table 6).
Note: PB0-PB3 can only output CMOS signals with an option for high slew rate.
However, PB4-PB7 can be configured as CMOS or Open Drain Outputs.
PC0 pin of Port C. This port pin can be configured to have the following functions:
MCU I/O – write to or read from a standard output or input port.
CPLD macrocell (McellBC0) output.
Input to the PLDs.
TMS Input
This pin can be configured as a CMOS or Open Drain output.
PC1 pin of Port C. This port pin can be configured to have the following functions:
MCU I/O – write to or read from a standard output or input port.
CPLD macrocell (McellBC1) output.
Input to the PLDs.
TCK Input
This pin can be configured as a CMOS or Open Drain output.
