This bit is set to "1".
2
SRST (Software ReSeT)
This bit is set to "1" in order to force the card to perform Task File
Reset operation. This does not change the Card Configuration
registers as a Hardware Reset does. The card remains in Reset
until this bit is reset to "0".
1
nIEN (Interrupt ENable)
This bit is used for enabling -IREQ. When this bit is set to "0", -IREQ
is enabled. When this bit is set to "1", -IREQ is disabled.
0
0
This bit is set to "0".
13. Drive Address register:
This register is read only register, and it is used for confirming the drive status.
This register is provides for compatibility with the AT disk drive interface. It is recommended that this
register is not mapped into the host’s I/O space because of potential conflicts on bit7.
