Default
THCV_GPIO0 1
SW = 0 (Off) = logic 0
SW = 1 (On) = logic 1
SW = 0 (Off)
THCV_GPIO1 2
SW = 0 (Off) = logic 0
SW = 1 (On) = logic 1
SW = 0 (Off)
THCV_GPIO2 3
SW = 0 (Off) = logic 0
SW = 1 (On) = logic 1
SW = 1 (On)
THCV_GPIO3 4
SW = 0 (Off) = logic 0
SW = 1 (On) = logic 1
SW = 0 (Off)
THCV_GPIO4 5
SW = 0 (Off) = logic 0
SW = 1 (On) = logic 1
SW = 0 (Off)
THCV_GPIO5 6
SW = 0 (Off) = logic 0
SW = 1 (On) = logic 1
SW = 0 (Off)
THCV_GPIO6 7
SW = 0 (Off) = logic 0
SW = 1 (On) = logic 1
SW = 0 (Off)
THCV_GPIO7 8
SW = 0 (Off) = logic 0
SW = 1 (On) = logic 1
SW = 0 (Off)
THCV242A GPIO signals are also routed to stake-pin headers (P10 and P11), as well as to LEDs. Logic ‘1’ on GPIO signal
turns on the corresponding LED.
2-wire master select
Image Output Board allows to select 2-wire bus master. Normally, CX-3 is a 2-wire bus master. Optionally, the AP can
serve as 2-wire master.
