pemnr
- MSWREN
Invalid when MSON is not 1 within the
same 80H command
Invalid when FLAG6=1
Invalid when OVFL=1
Invalid when a compare-connect start
command (MSDCN2=1 or MSDCN1=1)
occurs simultaneously
Direct connect if a compare-connect
sequence is already operating
When 0: Encode sequence stops
- MSWACL
When 1: Initializes the write address (WA)
When 0: No operation
- MSRDEN
When 1: Decode sequence starts
Does not perform decode sequence if
MSON=1.If there is no valid data, decode
sequence temporarily stops. But, because
the MSRDEN flag setting is maintained as
is, the sequence automatically re-starts
when valid data appears.
When 0: Decode sequence stops
-MSRACL
When 0: No operation
- MSDCN2, MSDCN1
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.
- WAQV
When 1: The immediately preceding YBLKCK
falling-edge timing WA (write address)
becomes the VWA (valid write address).
When 0: No operation
- MSON
When 1: Memory system turns ON and compres-
sion-type shock-proof operation starts
When 0: Memory system turns OFF and through-
mode playback starts. (In this mode, the
attenuator is still active.)
Write command supplementary information
80H (MS command)
81H (I/O setting on extension I/O)
82H (Setting output data on extension I/O)
