Table 2-2 MC9S12DP256 Power and Ground Connection Summary
2.4.7 VREGEN — On Chip Voltage Regulator Enable
Enables the internal 5V to 2.5V voltage regulator. If this pin is tied low, VDD1,2 and VDDPLL must be
supplied externally.

5.0 V
Operating voltage and ground for the analog-to-digital
converters and the reference for the internal voltage regulator,
allows the supply voltage to the A/D to be bypassed
independently.

2.5 V
Provides operating voltage and ground for the Phased-Locked
Loop. This allows the supply voltage to the PLL to be
bypassed independently. Internal power and ground
generated by internal regulator.
