All registers for the Two-Wire Serial interface 0, other than the Control
register, are accessed through Register 0xFD00. All registers for the
Two-Wire Serial interface 1, other than the Control register, are accessed
through Register 0xFD02. To select one of the three registers available
at address 0xFD00 or 0xFD02, write the desired value to the ES[0:2] bits
in the Control register (0xFD01 or 0xFD03). To conserve space, the
register descriptions only appear once in this chapter. The two applicable
locations are separated by a slash, with the Two-Wire Serial interface 0
address listed first.
Table
6.1, the register map, summarizes the Two-Wire Serial registers in
graphical form.
