Sega Saturn Sound Box (Model M) - Sega SATURN Device Manual Supplement

4. Dedicated CPU for Sound Control
· A 16-bit 11.3 MHz 68EC000 is used as the sound control CPU for the
SCSP. The 68EC000 is connected directly to the SCSP and operates independently
of the SH2. The interface also allows access of the SCSP from the SH2. During
access from the SH2, neither the SCSP nor 68000 CPU will stop. However, since
time-shared processing is used, the performance of the 68000 CPU will decrease
if there is frequent access from the SH2.

2. SEGA SATURN Sound Box (Model M)

The SEGA SATURN Sound Box (Model M) has two sets of MIDI IN, OUT and THRU
ports and a SCSI port, so it may be operated like a commercially available MIDI sound
module.
Also, beginning with version 1.21 of the sound driver, error codes can be output from
the MIDI OUT port, thus making it possible to detect data problems.
