4.16 Wide-Band Data/Control Register
This register is used for two functions, depending on whether it is being read from or written to. When read
from, the register provides the latest 8 bits of received and demodulated data according to the
microcontroller register map to the microcontroller. When it is written to, the bits are placed into the WBDCtrl
register (see Table 4–16) as shown here:
7 6 5 – 3 2 – 0
WBDCtrl WBD_LCKD WBD_ON WBD_BW[2:0] Reserved
W W W
When the WBDCtrl register is read, bit 7 (MSB) is the last received data bit.
The definition of the WBDCtrl register, according to the DSP register map, is shown in Table 4–18.
