Description
IF counter mode; IFCM reads 00 immediately after I
PRESET, SEARCH, AFU, JUMP or CHECK until the first IFC result of the
new tuning is available.

IF counter result; see
Rev. 03 — 19 March 2008
00 = no new counter result available (IFC value is previous result or
reset state)
01 = new counter result available (IFC value is new result)
10 = counter result from AF update (IFC value is AF result, value is
held until I
WAM and MOD shows AF update results.
11 = Power-On Reset (POR) or undefined state of the state machine is
detected. The I
0 = the IF counter result indicates a positive RF frequency error
1 = the IF counter result indicates a negative RF frequency error
0 = IF counter result with 1 kHz resolution in FM mode and 0.5 kHz
resolution in AM mode
1 = IF counter result with 8 kHz resolution in FM mode and 4 kHz
resolution in AM mode
