Function
This is a general-purpose I/O port.
This function becomes valid when data output from UART is
disabled.
This is a data output pin of UART.
This function becomes valid when data output from UART is
enabled.
This is a general-purpose I/O port.
This function becomes valid when clock output from UART is
disabled.
This is a clock I/O pin of UART.
This function becomes valid when clock output from UART is
enabled.
Because this input is used as required when UART is performing
input operations, and it is necessary to stop outputs by other
functions unless such outputs are made intentionally.
This is an output pin for the lower 8-bit of the external address bus.
E
This is an output pin for the middle 8-bit of the external address
bus.
This function is valid in the mode where the external bus is valid
and the middle address control refister is set to select an address.
E
This is a general-purpose I/O port.
This is a data input pin of I/O simple serial interface 1.
Because this input is used as required when I/O simple serial
interface 1 is performing input operations, and it is necessarey to
stop outputs by other functions unless such outputs are made
intentionally.
E
This is a general-purpose I/O port.
This function becomes valid when data output from I/O simple
serial interface 1 is disabled.
This is a data output pin of I/O simple serial interface 1.
This function becomes valid when data output from I/O simple
serial interface 1 is enabled.
E
This is a general-purpose I/O port.
This function becomes valid when clock output from I/O simple
serial interface 1 is disabled.
This is a clock output pin of I/O simple serial interface 1.
This function becomes valid when clock output from I/O simple
serial interface 1 is enabled.
