Dear all
In the '8.3.15.3' of DS90UB949 datasheet,it said GPIO_REG[8:5] are register-only GPIOs and may be programmed as outputs or read as inputs through local register bits only.
My issue:
1. GPIO_REG[8:5] must read by the software ?
2. GPIO[3:0] must read by the software only? I want to use GPIO2 to pass the interrupt signal from the deserial DS90UB938, My CPU don't want scan the signal,because it cost software resource.
