bit 7 bit 0

Legend: r = reserved bit

R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’

-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown

bit 15-8 CCB<15:8>: Command Code bits

The command code bits (10111000b) are serially sent to the microcontroller to identify the bits to be

written in the TXBREG.

bit 7-0 TXDB<7:0>: Transmit Data Byte bits

The transmit data bits hold the 8 bits that are to be transmitted. To use this register, set the bit,

TXDEN = 1 (GENCREG<7>). If TXDEN is not set, use the FSK/DATA/FSEL

pin to manually modulate

the data.
