General-purpose I/O port
This function is available when clock output of UART #0 and SSI #2
are disabled and corresponding bit of the upper address control
register specifies port.
External address bus output pin bit 20
This function is available when clock output of UART #0 is disabled
and corresponding bit of the upper address control register
specifies address.
UART #0 clock input pin
This function is available when the UART #0 clock output is
enabled.
General-purpose I/O port
This function is available when data output of SSI #2 is disabled
and corresponding bit of the upper address control register
specifies port.
External address bus output pin bit 21
This function is available when data output of SSI #2 is disabled
and corresponding bit of the upper address control register
specifies address.
Input capature #0 data input pin
This pin, as required, is used for input during input capture #0 input
operation, and it is necessary to disable input/output for other
functions from this pin unless such input/output is made
intentionally.
16-bit timer #0 data input pin
This pin, as required, is used for input during 16-bit timer #0 input
operation, and it is necessary to disable input/output for other
functions from this pin unless such input/output is made
intentionally.
General-purpose I/O port
This function is available when corresponding bit of the upper
address control register specifies port.
External address bus output pin bit 22
This function is available when corresponding bit of the upper
address control register specifies address.
Input capature #1 data input pin
This pin, as required, is used for input during input capture #1 input
operation, and it is necessary to disable input/output for other
functions from this pin unless such input/output is made
intentionally.
16-bit timer #1 data input pin
This pin, as required, is used for input during 16-bit timer #1 input
operation, and it is necessary to disable input/output for other
functions from this pin unless such input/output is made
intentionally.
