“I/F” notation in the table indicates that the register setting can be executed via Digital I/F.
[*1] Setting changes of R_BIAS_FBRT and R_MOD_FBRT are possible via Digital I/F, but APC_FB dividing coefficients K_BIAS_FBRT and K_MOD_FBRT are
not affected.
[*2] Register setting is possible but data is treated as “0”.
