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.

Description
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
Description
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.
