MIDI Control Register (MCNTL)
Loopback Mode Enable. When enabled, the MIDI receive signal is internally connected to the MIDI transmit
signal.
0: Disabled (default)
1: Enabled
MIDI Thru Enable. When enabled, the MDRX pin is internally connected to the MDTX pin, which then reflects
the MIDI receive signal. When disabled, the MDTX pin is driven with data coming from the MIDI Port transmit
engine.
0: Disabled (default)
1: Enabled
Reserved. Must be 0.
Pass-Thru Transmit Enable. When enabled, data is transmitted in Pass-Thru (non-UART) mode.
0: Disabled (default)
1: Enabled
Rx Data Ready Interrupt Enable. When enabled, an interrupt request is asserted in response to a Receive
Data Ready event.
0: Disabled
1: Enabled (default)
MDTX Pin Masking Enable. When enabled, the MDTX pin is constantly driven high by the MIDI Port. When
disabled, MDTX serves as the MIDI Port transmit line.
0: Disabled (default)
1: Enabled
Tx Buffer Empty Interrupt Enable. When enabled, an interrupt request is asserted in response to a Transmit
Buffer Empty event.
0: Disabled (default)
1: Enabled
Rx FIFO Enable for Pass-Thru Mode. When this bit is set to 1, the Receive FIFO is enabled in Pass-Thru
mode. This bit is ignored in UART mode.
0: Disabled
