22
// MPU/6850 mode is controlled by firmware, and we don't expect any
23
// firmware to have the secondary port operating in MPU mode.

// Quote:
25
// "When in MPU-401 emulation mode, RxRDY interrupts are ALWAYS enabled.
26
// For maximum compatibility when operating in MPU-401 emulation mode,
27
// the Host Interrupt Configuration register should be programmed to
28
// provide a separate interrupt for the MIDI Emulation, otherwise all
29
// other interrupts can be blocked by ill-behaved applications software.
30
// Because of this, MPU-401 mode may not generally be usable on the HOST
31
// interface, but is provided there purely for the sake of symmetry."
32
// "HOST interface" refers to the secondary port. The idea behind this
33
// paragraph is the model of having a basic SoundScape driver that handles
34
// basic SoundScape functionality (like mixer and wave via synth), but
35
// hands out an emulated MIDI port to an application that interfaces directly
36
// to an MPU401-like interface. If an application causes the MPU401 to
37
// provide a byte (like an ACK to various commands), and doesn't read it,
38
// the MPU401 interrupt is stuck active. If the driver operates on the same
39
// IRQ, it is unable to receive low-level IRQs while the MPU401 rx byte is
40
// pending.
