Hi, The attached patch make the SIG_UART_* names in the ioXXXX.h files consistent for all devices. If a device only has one uart, call it uart0. Uarts and usarts are both called uarts for simplicity. The hope is that this makes your uart code a bit more portable from one device to another and will make is easier for the developer to remember the correct name. Comments? Objections?
Objection:The UART and USART are quite different hardware. The USART can be used in a syncronous mode, which only applies to devices that support it. I struck this naming issue with the iom128.h recently which used UART instead of USART, was going to submit a patch for UART->USART :)
Naming should be as consistent as possible with datasheets so confusion can be avoided. If portability is required between the 2 flavours it can be done in other ways by the programmer.
