Functional Description (Continued)
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.
