4. Operating Modes
This section summarizes the settings for each operating mode of the SX1211, and explains the functionality
available and the timing requirements for switching between modes.

Active blocks
SPI, POR
SPI, POR, Top regulator, digital regulator, XO, CLKOUT (if activated through
OSCParam_Clkout)
Same + VCO regulator, all PLL and LO generation blocks
Same as FS mode + LNA, first mixer, IF amplifier, second mixer set, channel
filters, baseband amplifiers and limiters, RSSI, OOK or FSK demodulator,
BitSync and all digital features if enabled
Same as FS mode + DDS, Interpolation filters, all up-conversion mixers, PA
driver, PA and external VR_PA pin output for PA choke.
4.2. Digital Pin Configuration vs. Chip Mode
Table 13 describes the state of the digital IOs in each of the above described modes of operation, regardless of the
data operating mode (Continuous, Buffered, or Packet).

Notes:
(1): High-Z if Continuous mode is activated, else Output
(2): Output if PLL_lock_en = 1, else High-Z
(3): Valid logic states must be applied to inputs at all times to avoid unwanted leakage currents
