Functional Description
MICROWIRE INTERFACE
The programmable register set is accessed via the
MICROWIRE serial interface. The interface comprises three
signal pins: CLK, DATA, and LE (Latch Enable). 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) transi-
tions from LOW to HIGH, data stored in the shift registers is
loaded into the corresponding control register.
