B
(CMOS)
General-purpose I/O port
This function is valid when both the single-chip
mode and the hold function are disabled.
HRQ
Hold request input pin
This function is valid in the mode where the exter-
nal bus is valid or when the hold function is en-
abled.

B
(CMOS)
General-purpose I/O port
This function is valid when both the single-chip
mode and the external ready function are disabled.
RDY
Ready input pin
This function is valid when the external ready func-
tion is enabled in the mode where the external bus
is valid.

B
(CMOS)
General-purpose I/O port
This function is valid in the single-chip mode or
when the CLK output is disabled.
CLK
CLK output pin
This function is valid when CLK output is disabled
in the mode where the external bus is valid.

E
(CMOS/H)
General-purpose I/O port
This function is always valid.
SIN0
Serial data input pin of UART0
Because this input is used as required when
UART0 is performing input operations, and it is
necessary to stop outputs by other functions un-
less such outputs are made intentionally.

E
(CMOS/H)
General-purpose I/O port
This function is valid when serial data output from
UART0 is disabled.
SOT0
Serial data output pin of UART0
This function is valid when serial data output from
UART0 is enabled.
