From NS9215 Hardware Reference I know that all I/O are 5V tolerant. Is this true for FIM UART interface on CC 9P 9215 module?
I am asking because in my setup 9215 module restarts after some time (30 minutes) when I have serial devices connected to FIM UARTs.
The same module works without problems if serial devices are connected to ports 0 - 3.
Thanks you,
Stan
