AFC Limiter.
AFC limiter value.
Function
For the following registers (addresses 2Bh and 2Ch), use the following equation:
3×500[kHz]
ook_cnt_ val = _{Rb×(enmanch+1)}
where Rb's unit is in kHz and ―enmanch‖ is the Manchester Enable bit (found at address 71h bit [1]).
Therefore, the minimal data rate that this register can support without Manchester is 0.366 kbps.
