B
DTP/External interrupt request input pin
When DTP/external interrupts are enabled, these inputs may be used
suddenly at any time; therefore, it is necessary to stop output by other
functions on these pins, except when using them for output
deliberately.
When these pins are open in input mode, through current may leak in
stop mode/reset mode, be sure to fix these pins to V
CC
/V
SS
level to
use these pins in input mode.
ATG
10-bit A/D converter external trigger input pin
When these pins are open in input mode, through current may leak in
stop mode/reset mode, be sure to fix these pins to V
CC
/V
SS
level to
use these pins in input mode.
64
PB0
C
General-purpose I/O port
This function is valid when the UART0 (ch.0) serial data output
specification is “disabled”.
SOD0
UART0 (ch.0) serial data output
This function is valid when the UART0 (ch.0) serial data output
specification is “enabled”.
65
PB1
C
General-purpose I/O port
This function is always valid.
SID0
UART0 (ch.0) serial data input pin
During UART0 (ch.0) input operations, this input may be used
suddenly at any time; therefore, it is necessary to stop output by other
functions on this pin, except when using it for output deliberately.
66
PB2
C
General-purpose output port
This function is valid when the UART0 (ch.0) clock output
specification is “disabled”.
SCK0
UART0 (ch.0) clock output pin
The clock output function is valid when the UART0 (ch.0) clock output
specification is “enabled”.
UART0 (ch.0) external clock input pin. This function is valid when the
port is in input mode and the UART0 (ch.0) specification is external
clock mode.
67
PB3
C
General-purpose I/O port
This function is valid when the UART0 (ch.1) serial data output
specification is “disabled”.
SOD1
UART0 (ch.1) serial data output pin
This function is valid when the UART0 (ch.1) serial data output
specification is “enabled”.
68
PB4
C
General-purpose I/O port
This function is always valid.
SID1
UART0 (ch.1) serial data input pin
During UART0 (ch.1) input operations, this input may be used
suddenly at any time; therefore, it is necessary to stop output by other
functions on this pin, except when using it for output deliberately.
