●CCA operation during diversity

If CCA is executed during diversity operation, there is a case CCA_DONE ([CCA_CNTRL:B0 0x15(2)]) is not notified and

keep CCA operation. When executing CCA during diversity, set CCA-competion wait timer (case1), or once disabling

diversity before CCA execution (case 2).

Case 1: Set CCA completion wait timer

In IEEE standard, random buck off time

is required to resume CCA. However,

ML7396 family does not have rundum

back off time generator.
