– MSWREN
When 1: Write sequence starts
Invalid when MSON is not 1 within the
same 80H command
Invalid when FLAG6=1
Invalid when OVFL=1
If MSWREN = 1 command is issued during
compare-connect operation, MSDCN1 and
MSDCN2 must be set to 0. Write
sequence starts from the point the com-
mand is issued as direct-connect (CD-DA)
sequence.
When 0: Write sequence stops
– MSWACL
When 1: Initializes the write address (WA)
When 0: No operation
– MSRDEN
When 1: Read sequence starts
Does not perform read sequence if
MSON=1. If there is no valid data, read
sequence temporarily stops. But, because
the MSRDEN flag setting is maintained as
is, the sequence automatically re-starts
when valid data appears.
When 0: Read sequence stops
– MSRACL
When 1: Initializes the read address (RA)
When 0: No operation
– MSDCN2, MSDCN1
Refer to compare-connect sequence
After MSWACL and MSRACL, set MSWREN = 1
to start the write sequence. If the start occurs in
direct-connect mode, a noise may be generated.
CDDAMODE
When 1 and 1: 3-pair compare-connect sequence
starts
When 1 and 0: 2-pair compare-connect sequence
starts
When 0 and 1: Direct connect sequence starts
When 0 and 0: Compare-connect sequence stops.
No operation if a compare-connect
sequence is not operating.
VCD, SVCMODE
When 1 and 1: Video CD compare-connect
sequence, checking C2PO, starts (ASH
connect)
When 1 and 0: Video CD compare-connect
sequence, ignoring C2PO, starts (SH con-
nect)
When 0 and 1: Connect sequence, checking sync
data only, starts (S connect)
When 0 and 0: Compare-connect sequence stops.
No operation if a compare-connect
sequence is not operating.
– WAQV
When 1: If a write address (WA) is verified as a
valid at the preceding YBLKCK falling
edge timing, it becomes a valid write
address (VWA).
When 0: No operation
– MSON
When 1: Memory system turns ON and shock-
proof operation starts
When 0: Memory system turns OFF and through-
mode playback starts. Even in through
mode, the CDDAMODE and VCDMODE
settings may become active. VCDMODE
settings should be set if using C2PO.
