INV is usually an option on a "proper" UART or USART but not on a "serial communications module" or whatever they like to call it. If something has a true UART or USART module built in then it may well be supported. If it's only a simulated UART then it may not. What it does, of course, is to allow TXD and/or RXD to be inverted so that they can be connected to inverting line drivers and/or receivers.
