SFF-8067 Registers
This chapter contains descriptions of the LSI53C040 SFF-8067 registers.
The SCSI/DMA registers, Two-Wire Serial registers, Miscellaneous
registers, and System registers are described in
Chapter 6
are programmed to a binary one, while the terms “reset” or “clear” are
used to refer to bits that are programmed to binary zero. Any bits marked
as reserved should always be written to zero; mask all information read
from them. Reserved bit functions may change at any time. Unless
otherwise indicated, all bits in registers are active high, that is, the feature
is enabled by setting the bit. The bottom row of every register diagram
shows the default bit values, which are enabled after the chip is powered
on or reset.
