4、CRC16 verification
This function is enabled by default。
Write register 0x01[13] to turn on or off CRC functions。
When CRC is turned on but the AUTO - ACK function is not turned on , the chip reception
state is not affected by the CRC state , but the register has a CRC error status bit . After the PKT _
flag is pulled up , the MCU can read 0x16 × 15 bits to determine if the CRC is correct to
determine whether the frame data needs to be read .
If the CRC is on and the AUTO - ACK function is turned on , the chip will automatically
determine if the CRC is correct , and if the receiver PKT _ FLAG is pulled up , the packet is
received and the CRC is correct .
8、The application layer determines the package length
When register 0x01[2]= 0, the payload first byte has no special meaning, and the package
length is determined by the state of register 0x01 [1].
1、fw_term_tx=1
When register 0 x01 [1] = 1, when the firing data, the system will send FIFO write pointer and
read pointer, if the MCU to stop sending FIFO data written, chips will eventually detected when the
FIFO is empty, and then automatically exit status.
