FMCAP[7:0]
Bit 7-0:
FMCAP[7:0]: CAP bank value to control the FM RF frequency (coarse steps)
Note: 7 bit CAP value (Bit[7:6]: Combination 10b and 01b results in the same CAP-range)
Negative control: de RF frequency decreases when increasing the register’s value

Bit 7-4:
REV[3:0]: should be read as 0Dh
Bit 3-2:
Reserved[1:0]: should be read as all 1
Bit 1:
COV_FLG: counter overflow flag
0 = No overflow of the internal counter
1 = The last counting loop causes overflow of the internal counter
Bit 0:
AFC_FLG: AFC out of range bit
0 = AFC is within control range
1 = AFC is out of control range
Note: Reading this register will clear AFC, count 2 done interrupt.
COV_FLG is clear when CLR_CNT1 bit of CNT_CTRL register is high
