10. Alternate status register: This register is the same as Status register physically, so the bit assignment
refers to previous item of Status register. But this register is different from Status register that INTRQ is not
negated when data read.
11. Command register: This register is write only register, and it is used for writing the command at
executing the device operation. The command code is written in the command register, after the parameter is
written in the Task File registers during the disk is Ready state.
12. Device control register: This register is write only register, and it is used for controlling the disk
interrupt request and issuing an ATA soft reset to the disk.

SRST (Software ReSeT)
This bit is set to "1" in order to force the disk to perform Task File
Reset operation. Once the host sets SRST bit to "1", SRST bit must
be kept to "1" for at least 5
s. The disk remains in Reset until this
bit is reset to "0". While BSY bit is set to "1" in Status register as a
result of executing either the power-on or hardware reset protocol,
the host must not set SRST bit to "1" in Device Control register.
1
nIEN (Interrupt ENable)
This bit is used for enabling INTRQ. When this bit is set to "0",
INTRQ is enabled. When this bit is set to "1", INTRQ is disabled.
0
This bit is set to "0".
