To prevent data reception during CCA, follow the steps shown below. To restore data reception after CCA, be sure to return to the original setting before reception. [Procedure] (1) Setting to prevent bit synchronization from being established BANK2: 0x03 = 0x00 BANK2: 0x0E = 0x00 (2) CCA started (3) Waiting for CCA completion (4) After completion of CCA, TRX_OFF (1) Setting to establish bit synchronization BANK2: 0x03 = original value BANK2: 0x0E = original value
