NOTE:

Not to access SPI until TX completion. During packet transmission, if SPI access is attempted by the host, TX

data error can be expected.

[RX]

i) Continuous output mode (to host)

Set RXDIO_CTRL[1:0] ([DIO_SET: B0 0x0C(7-6)])=0b01.

After RX_ON (SET_TRX[3:0]([RF_STATUS: B0 0x0B(3-0)])=0x6) issued, during SCEN is ”H” period,

DCLK is output from SDO pin, RX data is output from SDI pin at falling edge of DCLK. After TRX_OFF

issuing(SET_TRX[3:0] ([RF_STATUS: B0 0x0B(3-0)])=0x8), DCLK/DIO output will stop. Even if

DCLK/DIO are output, when SCEN becomes “L”, DCLK/DIO will stop. (SPI access has a higher priority)

NOTE:

Not to access SPI until RX completion. During packet transmission, if SPI access is attempted by the host, RX

data error can be expected.
