• Calibrate when going from IDLE to
either RX or TX (or FSTXON)
14.12.1 Active Modes
The radio has two active modes: receive and
transmit. These modes are activated directly
by writing the SRX and STX command strobes
to the RFSTregister.
• Calibrate when going from either RX or
TX to IDLE automatically
• Calibrate every fourth time when going
from either RX or TX to IDLE
automatically
The frequency synthesizer must be calibrated
regularly. CC1110Fx/CC1111Fx has one manual
calibration option (using the SCALstrobe), and
three automatic calibration options, controlled
by the MCSM0.FS_AUTOCALsetting:
If the radio goes from TX or RX to IDLE by
issuing an SIDLEstrobe, calibration will not be
performed. The calibration takes a constant
number of XOSC cycles (see Table 72 for
timing details).
