Programming Information
The W3020 and W3000 transceiver mode (IC RX/TX) and the gain and band settings are programmed using a
standard three-wire bus (CLOCK, DATA, LATCH). The W3020 and W3000 registers are addressable so the two
ICs can share the same data, clock, and latch times. The LATCH line initiates download and execution of the
current DATA word.
