Register definitions
Figure E-1 shows that in bitmapped registers bit 7 is the high order
(leftmost) bit and bit 0 is the low order (rightmost) bit.

Table E-2 summarizes the S-Register set, valid parameter ranges, and
factory default values [n]. S-Registers listings followed by (SM) can
only be accessed when in Service Provider Mode, while those followed
by (RO) are read only and cannot be modified.
