Figure 7-4:
Using the 68HC05V7 with an External Regulator
If the regulator enable option is not selected, the MDLCPU option and the PDC bit have no
affect. The VDDC option will remain available.
Figure 7-5 is a block diagram of the regulator control circuit. It illustrates how the
MISCELLANEOUS register bits, VIGN, BUS and the Mask options interact in the power
moding scheme.
