4. Operating Modes
This section summarizes the settings for each operating mode of the SX1210, and explains the functionality
available and the timing requirements for switching between modes.
Table 10: Operating Modes
Table 11 describes the state of the digital IOs in each of the above described modes of operation, regardless of the
data operating mode.
Table 11: Pin Configuration vs. Chip Mode
Notes:
(1): High-Z if Continuous mode is activated, else Output
(2): Valid logic states must be applied to inputs at all times to avoid unwanted leakage currents
(3): Tie to Vss (or Vdd) when not in active receive mode.
(4): Output if PLL_lock_en = 1, else High-Z
