Subcode data processing
7.5.1
Q-
CHANNEL PROCESSING
The 96-bit Q-channel word is accumulated in an internal
buffer. The last 16 bits are used internally to perform a
Cyclic Redundancy Check (CRC). If the data is good, the
SUBQREADY-I signal will go LOW. SUBQREADY-I can
be read via the SDA or STATUS pins, selected via
register 2. Good Q-channel data may be read from SDA.

WIRE SUBCODE
(CD
GRAPHICS
)
INTERFACES
Data from all the subcode channels (P-to-W) may be read
via the subcode interface, which conforms to
EIAJ CP-2401. The interface is enabled and configured as
either a 3-wire or 4-wire interface via register F. The
subcode interface output formats are illustrated in Fig.7,
where the RCK signal is supplied by another device such
as a CD graphics decoder.
7.5.3
V4
SUBCODE INTERFACE
Data of subcode channels, Q-to-W, may be read via pin V4
if selected via register D. The format is similar to RS232
and is illustrated in Fig.8. The subcode sync word is
formed by a pause of (200/n)
μ
s minimum. Each subcode
byte starts with a logic 1 followed by 7 bits (Q-to-W). The
gap between bytes is variable between (11.3/n)
μ
s and
(90/n)
μ
s.
The subcode data is also available in the EBU output
(DOBM) in a similar format.
