P34
I
General I/O port with programmable pullup. This function is enabled
in the single-chip mode or when the hold function is disabled.
HRQ
Hold request input pin. This function is enabled when both the exter-
nal bus and the hold functions are enabled.
15
P35
I
General I/O port with programmable pullup. This function is enabled
in the single-chip mode or when the hold function is disabled.
HAK
Hold acknowledge output pin. This function is enabled when both
the external bus and the hold functions are enabled.
16
P36
I
General I/O port with programmable pullup. This function is enabled
in the single-chip mode or when the external ready function is dis-
abled.
RDY
Ready input pin. This function is enabled when both the external bus
and the external ready functions are enabled.
17
P37
H
General I/O port with programmable pullup. This function is enabled
in the single-chip mode or when the clock output is disabled.
CLK
CLK output pin. This function is enabled when both the external bus
and CLK outputs are enabled.
18
P40
G
General I/O port. This function is enabled when UART0 disables the
serial data output.
SOT0
Serial data output pin for UART0. This function is enabled when
UART0 enables the serial data output.
19
P41
G
General I/O port. This function is enabled when UART0 disables
clock output.
SCK0
Clock I/O pin for UART0. This function is enabled when UART0 en-
ables the clock output.
20
P42
G
General I/O port. This function is always enabled.
SIN0
Serial data input pin for UART0. While UART0 is operating for input,
the input of the pin is used as required. Except when the function is
intentionally used, output from the other functions must be stopped.
21
P43
G
General I/O port. This function is always enabled.
SIN1
Serial data input pin for UART1. While UART1 is operating for input,
the input of the pin is used as required. Except when the function is
intentionally used, output from the other functions must be stopped.
22
P44
G
General I/O port. This function is enabled when UART1 disables the
clock output.
SCK1
Clock pulse input/output pin for UART1. This function is enabled
when UART1 enables the clock output.
24
P45
G
General I/O port. This function is enabled when UART1 disables the
serial data output.
SOT1
Serial data output pin for UART1. This function is enabled when
UART1 enables the serial data output.
