（Characteristic FFE2）
Description
Control OUTPUT1 pin high level E7F101
Control OUTPUT1 pin low level E7F100
Control OUTPUT2 pin high level E7F201
Control OUTPUT2 pin low level E7F200
Control OUTPUT3 pin high level E7F301
Control OUTPUT3 pin low level E7F300
Control OUTPUT4 pin high level E7F401
Control OUTPUT4 pin low level E7F400
Control OUTPUT5 pin high level E7F501
Control OUTPUT5 pin low level E7F500
APP reads 5 output pin level E7FAFF Return E7FAFF0000000000
