UART
The UART contains three 8 bit registers. The data register can be read or written and is used to receive or
transmit MIDI information. The second register is a 8 bit control register which is write only. The third
register is a 8 bit status register which is read only.

Function
This bit is the UART receiver interrupt bit.
0 - No UART receiver interrupt
1 - UART receiver interrupt pending
These bits always read back as zeros to allow for soundscape
detection.
This bit is the UART transmitter interrupt bit
0 - No UART transmitter interrupt
1 - UART transmitter interrupt pending
This bit is the UART transmitter ready bit.
0 - UART transmitter not ready
1 - UART transmitter ready
This bit is the UART receiver ready bit.
0 - UART receiver not ready
1 - UART receiver ready
