15.12.1 Active Modes

The

CC1110 radio has two active modes:

receive and transmit. These modes are

activated directly by the CPU by writing the

SRX and STX command strobes to the RFST

The frequency synthesizer must be calibrated

regularly.

CC1110 has one manual calibration

option (using the SCAL strobe), and three

automatic calibration options. The automatic

calibration options are controlled by the

MCSM0.FS_AUTOCAL setting as follows:
