6、data packet payload length
Two ways to determine TX/RX package length. When register 0x01[2]= 1, the internal state of
the state can detect the package length according to the payload first byte data. If you want to send
8 bytes, the first byte should write 8 and the total word length is 9 bytes.
When register 0x01[2]= 0, the first byte data has no special significance. The packet length will
be determined by when the TX FIFO is empty or when the TX EN is cleared, see the table below.
0x01[2]
pack_length_en
0x01[1]
fw_term_tx
0
0
When TX EN= 0, terminate the launch.
When RX EN= 0, it terminates.
1
When FIFO is empty, automatically
terminates the launch
When RX EN= 0, it terminates。
1
x
The first byte of playload shows the length of the
packet , 0 to 64 bytes . When all data has been
sent , the transmission terminates automatically
Table 13-1
7、The state machine determines the length of the package
When register 0x01[2]= 1, the first byte of payload indicates the package length, and the
maximum length is 64 bytes
1、Launch timing
Below shows TX time series: when MCU writes register 0x00[15] to '1', and write register
0x00[6:0] to set up the transmitting channel, the chip will automatically generate the package
according to the payload. MCU needs to write the launch data before launching the trailer. College if
the packet length more than the length of the FIFO, MCU need to write a FIFO data many times.
FIFO flag (reg0x12[13]) indicates whether FIFO is empty.
