2.0 Programming Description
2.1 MICROWIRE INTERFACE
The 24-bit shift register is loaded via the MICROWIRE interface. The shift register consists of a 21-bit
DATA[20:0] FIELD
and a
3-bit
ADDRESS[2:0] FIELD
as shown below. TheADDRESS FIELD is used to decode the internal control register address. When
LE transitions HIGH, DATA stored in the shift register is loaded into one of 6 control registers depending on the state of the
ADDRESS bits. The MSB of DATA is loaded into the shift register first. The DATA FIELD assignments are shown in
Section 2.3

2.2 CONTROL REGISTER LOCATION
The ADDRESS[2:0] bits decode the internal register address. The table below shows how the ADDRESS bits are mapped into
the target control register.

2.3 CONTROL REGISTER CONTENT MAP
The control register content map describes how the bits within each control register are allocated to specific control functions. The
bits that are marked 0 should be programmed as such to ensure proper device operation.
