TTL
CMOS Bi-directional I/O port. Can be software
programmed for internal weak pull-up.
ST
—
Low voltage programming input pin. Interrupt-
on-pin change. When low voltage program-
ming is enabled, the interrupt-on-pin change
and weak pull-up resistor are disabled.
TTL
CMOS Bi-directional I/O port. Interrupt-on-pin
change. Can be software programmed for
internal weak pull-up.
TTL
CMOS ^{Bi-directional I/O port. Interrupt-on-pin}
change. Can be software programmed for
internal weak pull-up.
