I have a hardware solution where I can plug via I2C different modules. Some of these modules are serial interfaces with both SC16IS752 or SC16IS750, and dynamically add serial ports to the system.
The problem is I cannot figure out how to know if the device is a 2 UART chip or a single UART one.
Is there any register I can read from these chips to exactly know how many UARTs I'm getting?
Thanks in advance,
