2、Enter sleep mode and wake up
When the SPI CS pulls high, and the MCU writes register 0x01 [15], the chip enters the sleep
mode, and the current <1uA, the value of the register in the sleep mode can be maintained. When
SPI CS is low, the chip automatically wakes up into IDLE state. The MCU will pull the SPI CS for a
period (wait for crystal stability, about 1.5ms), and then write the SPI data.
3、Packet format
Air packet format
Preamble: 1~8 bytes,Can be set up.
SYNC: 16/32/48/64 bits, Can be set up.
Trailer: 4~18 bits, Can be set up..
Payload: TX/RX data. There are 4 data types:
Raw data
8bit/10bitlinecode
Manchester
Interleave with FEC option
CRC: 16-bit CRC is optional.
4、FIFO length
The default is 64 bytes, receive and send share, and can be set up to use 32 bytes to set
0x23[15] to 0, which USES 32 bytes each
