START

TX FIFO trigger level setting

If the TX data length is shorter than the

FAST_TX trigger level, TX will start by

writing all data to a FIFO.

[TX_ALARM_LH:B0 0x35] =0x00

[TX_ALARM_HL:B0 0x36] =0x00

Write TX data to FIFO

[WR_TX_FIFO:B0 0x7E]

CCA execution?

Go to CCA flowchart

If random back-off period specified in

the IEEE, go to CCA normal mode.

If IDLE is detected in minimum period,

go to CCA IDLE detection mode.

CCA result=BUSY?

TX data request accept completion int?

Yes

AUTO_RX_EN =0b1?

[AUTO_ACK_SET:B0 0x55(6)]

and

Send ACK request packet?

Go to RX flowchart

Yes

CCA continue?
