23.1.1. Operating Mode Control
There are four primary states in the EZRadioPRO transceiver radio state machine: SHUTDOWN, IDLE,
TX, and RX (see Figure 23.1). The SHUTDOWN state completely shuts down the radio to minimize current
consumption. There are five different configurations/options for the IDLE state which can be selected to
optimize the chip to the applications needs. "Register 07h. Operating Mode and Function Control 1" con-
trols which operating mode/state is selected with the exception of SHUTDOWN which is controlled by SDN
pin 20. The TX and RX state may be reached automatically from any of the IDLE states by setting the
txon/rxon bits in "Register 07h. Operating Mode and Function Control 1". Table 23.2 shows each of the
operating modes with the time required to reach either RX or TX mode as well as the current consumption
of each mode.
The transceivers include a low-power digital regulated supply (LPLDO) which is internally connected in
parallel to the output of the main digital regulator (and is available externally at the VR_DIG pin). This com-
mon digital supply voltage is connected to all digital circuit blocks including the digital modem, crystal oscil-
lator, SPI, and register space. The LPLDO has extremely low quiescent current consumption but limited
current supply capability; it is used only in the IDLE-STANDBY and IDLE-SLEEP modes. The main digital
regulator is automatically enabled in all other modes.
