○Continuous mode

Continuous CCA mode is executed by issuing RX_ON by [RF_STATU:B0 0x0B] register after setting

CCA_EN([CCA_CTRL: B0 0x39(4)])=0b1 and CCA_CPU_EN([CCA_CTRL: B0 0x39(5)])=0b1. In this

mode, CCA continues until CCA_STOP([CCA_CTRL: B0 0x39(7)])=0b1 is set. CCA completion interupt

(INT[18]: group3) is not generated. During CCA execution, CCA_RSLT([CCA_CTRL: B0 0x39(1-0)]),

[CCA_PROG_L: B0 0x3E], [CCA_PROG_H: B0 0x3D] are constantly updated. The value will be kept by

setting CCA_STOP([CCA_CTRL: B0 0x39(7)])=0b1.

*5CCA result can be read after

CCA_STOP execution.
