INT4
L
V
[INT4] External interrupt input. These
inputs are used continuously when the cor-
responding external interrupt is enabled. In
this case, do not output to these ports
unless doing so intentionally.
ATG
[ATG] External trigger input for A/D
converter. This input is used continuously
when selected as the A/D converter start
trigger. In this case, do not output to this
port unless doing so intentionally.
PG4
[PG4] General purpose input/output ports.
FRCK
[FRCK] External clock input pin for free-run
timer. This input is used continuously when
selected as the external clock input pin for
the free-run timer. In this case, do not out-
put to this port unless doing so intentionally.
(This function is only for MB91302A and
MB91V301A.)

INT5
LV
[INT5] External interrupt input. These
inputs are used continuously when the
corresponding external interrupt is enabled.
In this case, do not output to these ports
unless doing so intentionally.
SIN2
[SIN2] UART2 data input pin. This input is
used continuously when UART2 is perform-
ing input. In this case, do not output to this
port unless doing so intentionally.
PG5
[PG5] General purpose input/output port.
87
117
INT6
LV
[INT6] External interrupt input. This input is
used continuously when the corresponding
external interrupt is enabled. In this case,
do not output to these ports unless doing so
intentionally.
SOT2
[SOT2] UART2 data output pin. The pin has
this function when UART2 data output is
enabled.
PG6
[PG6] General purpose input/output port.
88
118
INT7
LV
[INT7] External interrupt input. This input is
used continuously when the corresponding
external interrupt is enabled. In this case,
do not output to these ports unless doing so
intentionally.
SCK2
[SCK2] UART2 clock input/output pin. The
pin has this function when UART2 clock
output is enabled.
PG7
[PG7] General purpose input/output port.
