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.

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.
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.
