HINT
EOP
If the LEN EN bit is set, then the contents of this register have no effect. If the LEN EN bit is cleared, then this register is used to configure how
an EOP (end of packet) condition is detected.
Bit 7
EOP Hint Enable. When set, this bit causes an EOP to be detected if no correlations have been detected for the number of
symbol periods set by the HINT field and the last two received bytes match the calculated CRC16 for all previously received
bytes. Use of this mode reduces the chance of noncorrelations in the middle of a packet from being detected as an EOP condi-
tion.
Bits 6:4
EOP Hint Symbol Count. The minimum number of symbols of consecutive noncorrelations at which the last two bytes are
checked against the calculated CRC16 to detect an EOP condition.
Bits 4:0
EOP Symbol Count. An EOP condition is deemed to exist when the number of consecutive noncorrelations is detected.

Function
CRC SEED LSB
The CRC16 seed allows different devices to generate or recognize different CRC16s for the same payload data. If a transmitter and receiver
use a randomly selected CRC16 seed, the probability of correctly receiving data intended for a different receiver is 1/65535, even if the other
transmitter/receiver are using the same SOP_CODE_ADR codes and channel.
Bits 7:0
CRC16 Seed Least Significant Byte. The LSB of the starting value of the CRC16 calculation.

Function
TX CRC LSB
Bits 7:0
Calculated CRC16 LSB. The LSB of the CRC16 that was calculated for the last transmitted packet. This value is only valid after
packet transmission is complete.
