Control Registers
Bit Duration Register (BDR)
Low-voltage and power-on events generated by the MFR4200 voltage
regulator cause the internal MFR4200 reset with the same consequences as
in the case of an external hard reset. Therefore, changes to the VREGSR bits
can be read by the host only after the MFR4200 leaves the internal reset
state.
