6.0 Musical Instrument Digital Interface (MIDI) Port
6.3 MIDI PORT REGISTERS
The following abbreviations are used to indicate the Register Type:
6.3.1
The following table lists the MIDI Port registers. For the MIDI Port register bitmap, see Section 6.4.
6.3.2
This read register is used for reading data received by the MIDI Port, and status information returned by the MIDI Port in
response to a previously issued command. When the FIFOs of the MIDI Port are enabled, reading from this offset returns
the next byte taken out of the Receive FIFO.
Location:
Type:
6.3.3
This write register is used for writing data to be transmitted by the MIDI Port. When the FIFOs of the MIDI Port are enabled,
writing to this offset puts the data byte into the Transmit FIFO.

R/W = Read/Write
R = Read from a specific address returns the value of a specific register. Write to the same address is to a different
register.
W = Write
RO = Read Only
R/W1C = Read/Write 1 to Clear. Writing 1 to a bit clears it to 0. Writing 0 has no effect.
