Functions
In addition to having the same functions as port P0 in the single-chip mode, these
pins also function as I/O pins for timers A0–A3, output pins for the real-time output,
and input pins for the key-input interrupt.
I/O In addition to having the same functions as port P0 in the single-chip mode, these
pins also function as I/O pins for timer A4, input pins for external interrupt inputs
____ ____
INT0–INT2, and input pins for timers B0–B2.
I/O In addition to having the same functions as port P0 in the single-chip mode, these
pins also function as input pins for the A-D converter, output pins for the D-A
converter, and input pins for INT2, INT3, and INT4.
I/O In addition to having the same functions as port P0 in the single-chip mode, these
pins also function as I/O pins for UART0, UART1, output pins for D-A converter,
and input pins for INT3 and INT4.
I/O s In single-chip mode
These pins have the same functions as port P0.
s In memory expansion and microprocessor modes
Address (A0–A7) is output.
I/O s In single-chip mode
These pins have the same functions as port P0.
s In memory expansion and microprocessor modes
Address (A8–A15) is output. Also, these pins function as I/O port pins according to
the register setting.
Input This pin is for a non-maskable interrupt.
