This 8 bit two’s complement value specifies a carrier phase offset of (n/128) where n is the two’s com-
plement value. This provides a range of phase offsets from - to *(127/128). (See Synthesizer/Mixer
Section).
Reserved.
When Test Mode enabled*, SPH4-0 is forced to the values programmed in these bit locations. Bit position
4 maps to SPH4. (See Test Mode Section).
When Test Mode enabled*, SSTRB is forced to state of this bit.
When Test Mode enabled*, HI/LO is forced to state of this bit.
When Test Mode enabled*, IOUT9-0 if forced to the values programmed in these bit locations. Bit position
16 maps to IOUT9.
When Test Mode enabled*, DATARDY is forced to state of this bit.
When Test Mode enabled*, LOTP is forced to state of this bit.
When Test Mode enabled*, QOUT9-0 is forced to the values programmed in these bit locations. Bit posi-
tion 16 maps to QOUT9.
Reserved.
Writing this address samples the accumulator in the AGC’s Loop Filter. The procedure for reading the
sampled value out of the part on C0-7 is discussed in the Microprocessor Interface Section. (See Micro-
processor Interface Section).
