Setup 1: AFC and AGC are configured to lock on preamble detection by setting AFC_LOCK_MODE = 3 and AGC_LOCK_MODE = 3.
Setup 2: AFC and AGC are configured to lock on sync word detection by setting AFC_LOCK_MODE = 3, AGC_LOCK_MODE = 3, and PREAMBLE_MATCH = 0.
Setup 3: AFC is disabled and AGC is configured to lock on sync word detection by setting AFC_LOCK_MODE = 1, AGC_LOCK_MODE = 3, and PREAMBLE_MATCH = 0.
For Setup 2 and Setup 3, sync word length is 24 bits. Sync word detect length has an impact on minimum preamble length.
The AGC high threshold is configured by writing to the AGC_HIGH_THRESHOLD register (Address 0x35F). The AGC low threshold is configured by writing to the
AGC_LOW_THRESHOLD register (Address 0x35E). The AGC clock divide is configured by writing to the AGC_CLK_DIVIDE register (Address 0x32F). Note that the
accuracy of the RSSI readback is degraded with these modified AGC threshold settings.
The AFC is enabled or disabled by writing to the AFC_LOCK_MODE setting in register RADIO_CFG_10 (Address 0x116). The AFC Ki and Kp parameters are configured
by writing to the AFC_KP and AFC_KI settings in the RADIO_CFG_11 register (Address 0x117).
The transmit preamble length (in bytes) is set by writing to the PREAMBLE_LEN register (Address 0x11D).
The sync word error tolerance (in bits) is set by writing to the SYNC_ERROR_TOL setting in the SYNC_CONTROL register (Address 0x120).
