○DIO output mode 2 operation

While RXDIO_CTRL[1:0]=0b11, RX data (after L-field) will be stored into the RX_FIFO. RX data stored in

the RX_FIFO is output through DIO pins, if setting DIO_START ([DIO_SET: B0 0x0C(0)])=0b1. Upon

outputting RX data defined by L-field, RX is completed and generate RF completion interrupt (INT[8] group2).

In case of TRX_OFF, issuing TRX_OFF by [RF_STATUS:B0 0x0B] register.

*3: Please refer to RF state transition wait flow

*2: Preamble, SyncWord and Error tolerance are set

by following registers.

Preamble

[DATA_SET1: B0 0x07]

[SYNC_CONDITION1-3: B0 0x45-47]

SyncWord [SYNCWORD1_SET0-3: B1 0x27-2A]

[SYNCWORD2_SET0-3: B1 0x2B-2E]

[SYNC_WORD_LEN: B1 0x25]

[DATA_SET2: B0 0x08]

*5 RX data must be transferred to the HOST

at rising edge of DCLK.

*1 DIO/DCLK pins are defined as follows:

[GPIO0_CTRL: B0 0x4E]

[GPIO1_CTRL: B0 0x4F]

[GPIO2_CTRL: B0 0x50]

[GPIO3_CTRL: B0 0x51]

[EXT_CLK_CTRL: B0 0x52]

[SPI/EXT_PA_CTRL: B0 0x53]

Preamble/SyncWord

Error tolerance setting *2

START

RX_ON issue *3

[RF_STATUS: B0 0x0B]

Yes

TRX_OFF issue

[RF_STATUS: B0 0x0B]

Read RX data *5

(DIO pins)

Yes

Next packet to be RX?

RXDIO_CTRL setting=0b11

[DIO_SET: B0 0x0C(7-6)]

DIO_START =0b1

[DIO_SET:0B 0x0C(0)]

Yes

SyncWord Detection (INT[13])?

[INT_SOURCE_GRP3: B0 0x0F(5)]

To RF state transition wait flow

DCLK output?

(DCLK function pin)

Yes

Wait *4

*4 Wait time should be more than Length field

+ 1 byte data receiving period.

1 byte data is decoded 8 bit data. If using

Manchester code, 1 byte period becomes

160

μs (@ 100kbps).

DIO pins setting *1

RX completion (INT[8])?

[INT_SOURCE_GRP2: B0 0x0E(0)]
