2.1.2 Power Control Modes - AMPS
When operating in AMPS mode the ZL20200 will operate in either Receive only or Duplex. The enable registers
should therefore be programmed as shown below.
Note 1:
Not required if driving external receive mixer direct from UHF VCO.
The receive register contains all bits required when in receive mode: the transmit register contains all bits required
in duplex mode. The Enable1 configuration register contains all bits required to power up oscillators and
synthesizers in both receive and duplex mode. The Enable2 configuration register contains all bits required to
power up the complete receive and duplex modes (this register can be set to all '1's if preferred).
The following words should therefore be programmed on the serial bus (Hex format):
