B7: Modulator burst window output enable bit.
1/The timing of the I and Q baseband modulation output burst is output at the TXCO pin.
0/The 384 kHz transmit timing clock pulse is output at the TXCO pin.
B6 to B4: ICT6 to ICT4. Device test control bits.
B3, B2: Local inverting mode setting bits.
(1, 1) = local inverting mode
(0, 0) = normal mode
B1: Clock pulse shaping mode selection bit.
1/Clock pulse shaping mode (Refer to Fig 9.)
0/Oscillator circuit mode
B0: Power-on control bit for X1, X2 pins, when the clock pulse shaping mode.
1/ Always power-on
0/ Power-down in the whole device power-down state when Power on otherwise.
Note: CR5 – B6 to B4 are used to test the device. They should be set to “0” during normal
operation.
