Data
Transmit Data. The over-the-air transmitted order is bit 0 followed by bit 1, followed by bit 2, followed by bit 3, followed by bit 4,
followed by bit 5, followed by bit 6, followed by bit 7.

Valid
The Valid bits are used to determine which of the bits in the Transmit SERDES Data register (reg 0x0F) are valid.
1 = Valid transmit bit.
0 = Invalid transmit bit.

PN Codes
The value inside the 8 byte PN code register is used as the spreading code for DSSS communication. All 8 bytes can
be used together for 64 chips/bit PN code communication, or the registers can be split into two sets of 32 chips/bit PN
codes and these can be used alone or with each other to accomplish faster data rates. Not any 64 chips/bit value can
be used as a PN code as there are certain characteristics that are needed to minimize the possibility of multiple PN
codes interfering with each other or the possibility of invalid correlation. The over-the-air order is bit 0 followed by bit 1...
followed by bit 62, followed by bit 63.
Note:
6.
Note: The Valid bit in the Transmit SERDES Valid register (Reg 0x10) is used to mark whether the radio will send data or preamble during that bit time of the
data byte. Data is sent LSB first. The SERDES will continue to send data until there are no more VALID bits in the shifter. For example, writing 0x0F to the
Transmit SERDES Valid register (Reg 0x10) will send half a byte.
