MICROWIRE INTERFACE

The programmable register set is accessed via the

MICROWIRE serial interface. The interface comprises three

signal pins: CLK, DATA, and LE. Serial data (DATA) is

clocked into the 24-bit shift register on the rising edge of the

clock (CLK). The last bits decode the internal control register

address. When the Latch Enable (LE) transitions from LOW

to HIGH, data stored in the shift registers is loaded into the

corresponding control register.
