3.5.3 Control Register Definitions
The host interface internal registers are divided into three classes: User
Configurable (UC), Auto-Configurable (AC), and Read-Only (RO). Address
locations 0 through 14 contain parameters which may be configured by the user.
Locations 15 through 31 are automatically configured based on the STD[4:0] and
MODE[2:0] registers, but can be user configured if desired.
Address 0 contains three status registers LOCK_32, FF_DETECT, and
SEQUENCE[3:0] which can only be read. Writing to the read-only registers will
have no effect on their contents.
