Table 7.
After a tuning action, which is activated by the state machine, the IF counter is reset at
that moment when tuning is established (PLL in-lock). The first counter result is available
from 2 ms after reset. For FM further results can be obtained from 4 ms, 8 ms, 16 ms and
32 ms after reset, the increasing count time attenuates influence of FM modulation on the
counter result. After this, the counter continues at the maximum count time of 32 ms (see

After AF Update (AFU) sampling the IF counter read value is held (IFCM = 10) (see
