Memory Map/Register Definition
UART registers are accessible only as bytes.
Interrupt can mean either an interrupt request asserted to the CPU or a
DMA request.
UART Mode Registers
(Read) UART Status Registers (USRn)
(Write) UART Clock Select register
(Read) Do not access
(Write) UART Command Registers (UCRn)
(UART/Read) UART Receive Buffers (URBn)
(UART/Write) UART Transmit Buffers (UTBn)
