MC9S12DT128 Device User Guide — V02.09

2.4.4 VDDA, VSSA — Power Supply Pins for ATD and VREG

VDDA, VSSA are the power supply and ground input pins for the voltage regulator and the analog to

digital converter. It also provides the reference for the internal voltage regulator. This allows the supply

voltage to the ATD and the reference voltage to be bypassed independently.

2.4.5 VRH, VRL — ATD Reference Voltage Input Pins

VRH and VRL are the reference voltage input pins for the analog to digital converter.

2.4.6 VDDPLL, VSSPLL — Power Supply Pins for PLL

Provides operating voltage and ground for the Oscillator and the Phased-Locked Loop. This allows the

supply voltage to the Oscillator and PLL to be bypassed independently.This 2.5V voltage is generated by

the internal voltage regulator.

NOTE:

No load allowed except for bypass capacitors.

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.
