HDERA - Header Erasure
This bit is high if there is at least one erasure flag detected in header bytes excluding mode
byte. Erasure in mode byte will cause RMOD (0Eh.r7-4) all become high.
SHDERA - Subheader Erasure
This bit is high if erasure flags are detected for both bytes in at least one subheader byte-
pairs.
Erasures are latched from pin C2PO it BUFEN (0Ah.w2) is disabled. Otherwise, header and
subheader bytes are retrieved from external RAM while the following sector is being buffered.
