Type
These pins make up Port A. These port pins are configurable and can have the following
functions:
1. MCU I/O – write to or read from a standard output or input port.
2. CPLD macrocell (McellAB0-7) outputs.
3. Inputs to the PLDs.
4. Latched address outputs (see Table 5).
5. Address inputs. For example, PA0-3 could be used for A0-A3 when using an 80C51XA
in burst mode.
6. As the data bus inputs D0-D7 for non-multiplexed address/data bus MCUs.
7. D0/A16-D3/A19 in M37702M2 mode.
8. 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:
1. MCU I/O – write to or read from a standard output or input port.
2. CPLD macrocell (McellAB0-7 or McellBC0-7) outputs.
3. Inputs to the PLDs.
4. Latched address outputs (see Table 5).
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:
