I have some doubts about the GPIO configuration of DS90UB947 and DS90UB948.
Our solution is: GPIO of CPU controls peripherals through 947 and 948.
Current testing: GPIO2, GPIO3, GPIO8 control peripherals of UB947, UB948 have no problems, GPIO5, GPIO6 control peripherals have problems.
UB947, GPIO5 and GPIO6 are set as input, read register 0x1c, state GPIO5 and GPIO6 are 1.
UB948, GPIO5 and GPIO6 are set as output and enable remote, and GPIO5 and GPIO6 are measured as low level.
UB948, GPIO5 and GPIO6 are set to local output, so there is no problem with the control peripheral.
Look at the datesheet with the following description:
Is it because GPIO [5-8] can't be used like this? Or is there a problem with configuration?
