Two-Wire Serial
Registers
This chapter contains descriptions of the LSI53C040 Two-Wire Serial
interface registers. The SCSI/DMA registers, SFF-8067 registers,
Miscellaneous registers, and System registers are described in
Chapter
bits that 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. 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.
