Product data sheet
8.1.1 Read mode: data byte IFCOUNTER
8.1 Read mode
Table 4.
Application restriction to use the read mode: Read transmissions should not be
stopped after read byte 4 (IFBW) since this will disturb level read-out, weak signal
processing and bandwidth control. Read transmission can be stopped after any of the
other read bytes 0 to 3, 5 or 6.
The read data is loaded into the I
the data byte.

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 sign
Rev. 03 — 20 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
