B7 to B4: ICT7 to ICT4. Device test control bits.

B3, B2

: Local inverting mode setting bits. (Used when the phase of the demodulator IF

input to this device is inverted.)

(1, 1) = local inverting mode

(0, 0) = normal mode

B1, B0 : ICT1, ICT0. Device test control bits.

Note: CR5 - B7 to B4, B1, and B0 are used to test the device. They should be set to “0” during

normal operation.
