H'0000 R/W Sector
Transfer Count Specification
Specify the number of sectors to be read continuously
in sector access mode. These bits are counted down for
each sector transfer end and stop when they reach 0. In
command access mode, these bits become H'0001.
When accessing one sector, set H'0001 to the
SCTCNT.
Note:
