Description
These are 8 bit I/O ports with the same functions as P0.
The middle 8 bits (A8 to A15) of the address are put out.
With an external data bus width of 16 bits and multiplex bus setting, time sharing is performed for data (D7)
I/O and address (A8) output. Address (A9 to A15) output also is performed.
Impress 2.7 V to 5.5 V.
Impress 0 V.
These are 8 bit I/O ports with the same functions as P0.
Output of the lower 8 bits (A0 to A7) of the address is performed.
With an external data bus width of 16 bits and multiplex bus setting, time sharing is performed for data (D0
to D7) I/O and address lower 8 bits (A0 to A7) output.
With an external data bus width of 16 bits and multiplex bus setting, time sharing is performed for data (D0
to D6) I/O and address (A1 to A7) output. Address (A0) output also is performed.
These are 8 bit I/O ports with the same functions as P0.
Data (D8 to D15) I/O is performed at the time of separate bus setting.
These are CMOS 8 bit I/O ports. They have direction registers for I/O selection, and input or output port setting
is possible individually for each terminal. For an input port, the existence or absence of a pull-up resistance
can be set by software in 4 bit units.
Data (D0 to D7) I/O is performed at the time of separate bus setting.
This are 8 bit I/O ports with the same functions as P0. By software selection, they function as input terminals
of the A/D converter. P104 to P107 also function as input terminals for the key input interrupt function.
This is the A/D converter power supply input terminal. Please connect it to the Vss terminal.
This is the A/D converter reference voltage input terminal.
This is the A/D converter power supply input terminal. Please connect it to the Vcc terminal.
