Description

Conditions under which the SBQS is placed in "L"

(a) When the CRC checked results is good.

(b) When both subcode sync signals S0 and S1 are detected in the

specified position

When both conditions (a) and (b) above are satisfied, the SBQS pin

outputs "L".

If SBQS does not turn to "L" then the subcode ready status indicates

"H" (=not ready).When the subcode ready status is "H",the

microcomputer can not read a valid subcode Q-channel data from

the M65824AFP.

The subcode-Q data is renewed at the same timing of the signal

"SBQS" s tatus is "L".

When the microcomputer send a subcode ready s tatus command,if

the s ignal "MLAB" is changed from "H" to "L" during the signal

"SBQS" s tatus is "L" then the M65824AFP will return the status

not ready. (status="H")

While the latch line "MLAB" is remained "L", the subcode-Q data

is not renewed.

The M65824AFP output a subcode-Q data with reversed each 1-byte.

(8)Subcode interface R-W

The subcode data(P,Q,R,S,T,U,V,W) can be read from the SBCO pin

by inputting clocks to the SCCK pin among the data converted from

14-bit EFM signal to 8-bit symbol.

When both subcode sync. patterns S0,S1 are detected in the

specified position as a sync. signal of this subcode, a sync.

signal is output from SCAND pin.

If 8 or more clocks are input to the SCCK, the SBCO is placed in "L".
