GPIO7, GPIO8
General-Purpose Input/Output 7 and General-Purpose Input/Output 8.
GPIO_s can be configured to act as a TTL input, a push-pull, open-drain, or
high-impedance output or a pulldown circuit during a fault event or reverse
sequencing.

GPIO1–GPIO6
General-Purpose Input/Output 1–General-Purpose Input/Output 6. GPIO_s
can be configured to act as a TTL input, a push-pull, open-drain, or high-
impedance output or a pulldown circuit during a fault event.
