Operation of the HCTL-1100
Registers
The HCTL-1100 operation is
controlled by a bank of 64 8-bit
registers, 35 of which are user
accessible. These registers
contain command and configura-
tion information necessary to
properly run the controller chip.
The 35 user-accessible registers
are listed in Tables 1 and 2. The
register number is also the
address. A functional block
diagram of the HCTL-1100 which
shows the role of the user-
accessible registers is also
included in Figure 3. The other 29
registers are used by the internal
CPU as scratch registers and
should not be accessed by the
user.
