CONTROL BUS
The ZIF600 has its synthesiser and demodulator configured
by a three wire control bus (CLOCK, DATA, LE). The ZIF600
must have these commands applied to it before it can be used.
Each command must be complete. Data is clocked into the
ZIF600 on the rising edg of the clock. Data is latched into the
internal registers when ENABLE is high. Since the ENABLE pin
gives a direct load and also resets some circuits, there will be
a phase discontinuity if data is loaded after the synthesser has
settled. The bus clock does not need to run between messages
and to minimise interference to radio receiver circuits it is
recommended that the clock is stopped whenever it is not
needed. Fig. 7 shows the format of the control bus.
