4.0 MCM20014 Utility Programming Registers
4.1 Register Reference Map
The I
2
C addressing is broken up into groups of 16 and
assigned to a specific digital block. The designated
block is responsible for driving the internal control bus,
when the assigned range of addresses are present on
the internal address bus. The grouping designation and
assigned range are listed in
Table 1
. Each block con-
tains registers which are loaded and read by the digital
and analog blocks to provide configuration control via
the I
2
C serial interface.
Table 2
contains all the I
2
C address assignments. The
table includes a column indicating whether the register
values are shadowed with respect to the sensor inter-
