2.0 Programming Description
2.1 MICROWIRE INTERFACE
The 22-bit shift register is loaded via the MICROWIRE interface. The shift register consists of a 20-bit
Data[19:0] Field
and a 2-bit
Address[1:0] Field
as shown below. The Address 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 4 control registers depending on the state of the address
bits. The MSB of Data is loaded in first. The Data Field assignments are shown in
Section 2.3 CONTROL REGISTER CONTENT

2.2 CONTROL REGISTER LOCATION
The address bitsAddress[1:0] decode the internal register address. The table below shows how the address bits are mapped into
the target control register.
