5.4.5 EDC Checking
The EDC checking logic carry 32-bit CRC checking on error corrected data according to its mode.
The checking result can be monitored through flag
CRCOK (0Ch.r7)
. If the result is error, the errors
in sector may exceed the capacity of correction logic and some data might be miscorrected.
5.4.6 Real Time EDC Checking
If real time EDC checking logic is enabled by setting
RTEDC (0Ah.w6)
high, the remainder of serial
data is calculated while the sector is being buffered into DRAM. The sector ready interrupt flag
SRIb
(01h.r5)
is immediately activated at next sync if the resultant remainder is zero, i.e., no EDC error. If
there is error, the specified error correction is then applied to the buffered data. This function should
not be enabled in disk-monitor mode.

5.4.8 Disc Format Selection
Before enable decoder logic through register
CTRL0 (0Ah,w)
, appropriate value should be set to
register
CTRL1 (0Bh.w)
according to different disc format. If
ACEN (0Ah.w4)
and
M2RQ (0Bh.w3)
are both high, the type of error correction is automatically determined by FORM bit in the subheader
byte rather than setting of
F2RQ (0Bh.w2)
. The value of
ACEN (0Ah.w4)
does not affect the yellow-
book mode-1 correction.
