Revision 0.61

Bit 1:

DRST - Decoder Reset

Setting this bit to high resets decoding logic, including:

• SRIEN (01h.w5) ← 0

• CTRL0 (0Ah,w) ← 00h

• CTRL1 (0Bh,w) ← 00h

• CTRLW (10h,w) ← 00h

• STAT0-2 (0Ch-0Eh,r) ← 00h

• STAT3 (0Fh,r) ← 80h

• TARSTA (80h,r) ← 00h

DRST is automatically cleared by itself.

CRTRG - Correction Retry Trigger - (write 11h)

Writing register CRTRG, regardless of what data is written, triggers the decoding logic to perform

another correction sequence to the same block.

Bit 7-1: Reserved

Bit 0:

CRRL - Correction Retry Register Load

Setting this bit high while writing register CRTRG (11h,w) re-loads the setting of EDCEN

(0Ah.w5), QCEN (0Ah.w1), or PCEN (0Ah.w0) to decoding logic.
