Function
P34
14
HRQ
B
(CMOS)
General-purpose I/O port
This function is valid when both the single-chip
mode and the hold function are disabled.
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.
P35
15
HAK
B
(CMOS)
General-purpose I/O port
This function is valid when both the single-chip
mode and the hold function are disabled.
Hold acknowledge output pin
This function is valid in the mode where the exter-
nal bus is valid or when the hold function is en-
abled.
P36
16
RDY
B
(CMOS)
General-purpose I/O port
This function is valid when both the single-chip
mode and the external ready function are disabled.
Ready input pin
This function is valid when the external ready func-
tion is enabled in the mode where the external bus
is valid.
P37
17
CLK
B
(CMOS)
General-purpose I/O port
This function is valid in the single-chip mode or
when the CLK output is disabled.
CLK output pin
This function is valid when CLK output is disabled
in the mode where the external bus is valid.
P40
General-purpose I/O port
This function is always valid.
18
SIN0
E
(CMOS/H)
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.
P41
19
SOT0
E
(CMOS/H)
General-purpose I/O port
This function is valid when serial data output from
UART0 is disabled.
Serial data output pin of UART0
This function is valid when serial data output from
UART0 is enabled.
