2.18 MIDI PORT (MIDI) CONFIGURATION
This section applies to the PC87393 and PC87393F only.
2.18.1
Logical Device 12 (MIDI) Configuration
Table 26 lists the configuration registers which affect the MIDI Port. Only the last register (F0h) is described here. See Sec-
tions 2.2.3 and 2.2.4 for a detailed description of the others.

2.18.2
MIDI Port Configuration Register
This register is reset by hardware to 00h.
Location:
Index F0h
Type:
R/W
Usage Hints: To operate MIDI enhanced features, make sure to locate its base address within the LPC Wide Generic ad-
dress range.
When bit 3 of the MIDI configuration register is set to 0 (default), the MIDI operates in Legacy mode. In this mode, only the
MIDI IN, MIDI OUT, MIDI Status and MIDI Command registers of the MIDI are user-accessible.
When bit 3 of the MIDI configuration register is set to 1, the MIDI is operated in Enhanced mode. In this condition, all the
registers listed in the MIDI chapter are accessible.
