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.
