Why are 8-bit values, such as THR, defined as 8-bit values for all but UART4, which is defined as a 32-bit value?
All the fields in the LPC_UART4_TypeDef are defined as 32-bit values, but not the other UART typedefs. The datasheet shows the same info for fields like THR for all the different types of UARTs, but this header file defines them differently. This causes issues for my generic UART class, that I can work around by typecasting, but this seems like these are errors in your header file.
