Function

A Crystal oscillation pins (16 MHz)

D Operation mode specification input pins

Connect directly to VCC or VSS.

G External reset request input

E Hardware standby input pin

C General-purpose I/O ports

This function is valid only in single-chip mode.

Output pins for low-order 8 bits of the external address bus.

This function is valid only in modes where the external bus is

enabled.

C General-purpose I/O ports

This function is valid only in single-chip mode or when the external bus

is enabled and the 8-bit data bus specification has been made.

I/O pins for higher-order 8 bits of the external data bus

This function is valid only when the external bus is enabled and the

16-bit bus specification has been made.

C General-purpose I/O ports

This function is valid only in single-chip mode.

Output pins for lower-order 8 bits of the external address bus

This function is valid only in modes where the external bus is

enabled.

C General-purpose I/O ports

This function is valid either in single-chip mode or when the address

mid-order control register specification is “port”.

Output pins for mid-order 8 bits of the external address bus

This function is valid in modes where the external bus is enabled and

the address mid-order control register specification is “address”.

C General-purpose I/O ports

This function is valid either in single-chip mode or when the address

high-order control register specification is “port”.

Output pins for higher-order 8 bits of the external address bus

This function is valid in modes where the external bus is enabled and

the address high-order control register specification is “address”.

C General-purpose I/O ports

This function is valid when either single-chip mode is enabled or the

address higher-order control register specification is “port”.

Output pins for higher-order 8 bits of the external address bus

This function is valid in modes where the external bus is enabled and

the address higher-order control register specification is “address”.

16-bit reload timer input pins

This function is valid when the timer input specification is “enabled”.

The data on the pins is read as timer input (TIN1 to TIN5).
