●RX mode (DIO mode)

DIO (RX) mode can be selected by setting DIO_EN ([PLL_MON/DIO_SEL:B0 0x69(1)]) =0b1 and RX_FIFO_MON

([PLL_MON/DIO_SEL:B0 0x69(1)]) =0b1. In DIO (RX) mode, when issuing RX_ON command, preamble and SFD

detection will be started. After preamble and SFD are detected, RX data is output through DIO pin (#15). RX Data following

SFD field are output and RX data should be read at rising edge of DCLK from DCLK pin (#16). After RX completion,

TRX_OFF commnand should be issued.

Like packet mode, preamble and SFD detection are done according to the settings of [PREAMBLE_SET:B0 0x39],

[SFD1_SET1:B0 0x3A] to [SFD1_SET4:B0 0x3D], [RX_PR_LEN/SFD_LEN:B0 0x43] and [SYNC_CONDITION:B0 0x44]

registers.After SFD is deteceted, SFD detection interrupt (INT[11] group2) will generate.

The first RX data is output at the first rising edge of DCLK after SFD detection interrupt notification.(Timing from SFD

detection interrupt to the first DCLK rising edge is 9μs at 100kbps setting.)

START

Set DIO_EN =0b1

RX_FIFO_MON =0b1

[PLL_MON/DIO_SEL:B0 0x69(1,0)]

Detect condition setting

* Like packet mode, detect pattern should be

set to ([PREAMBLE_SET:B0 0x39] and

[SFD_SET1-4:B0 0x3A-3D] registers.

[PREAMBLE_SET:B0 0x39]

[SFD1_SET1-4:B0 0x3A-3D]

[RX_PR_LEN/SFD_LEN:B0 0x43]

[SYNC_CONDITION:B0 0x44]

Note: Different from DIO (TX) mode setting.

RX_ON issue

[RF_STATUS:B0 0x6C]

END

Yes

DCLK output?

* Afetr entering RX_ON state, DCLK will be

output regardless of RX data.

[DCLK pin (#16)]

Read RX data

* RX data should be read at rising edge of

DCLK.

[DIO pin (#15)]

TX completion?

TRX_OFF issue

[RF_STATUS:B0 0x6C]
