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 reference and the
analog to digital converter.
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.
Table 2-2 MC9S12C-Family Power and Ground Connection Summary
NOTE:All VSS pins must be connected together in the application. Because fast signal transitions
place high, short-duration current demands on the power supply, use bypass capacitors with
high-frequency characteristics and place them as close to the MCU as possible. Bypass requirements
depend on MCU pin load.

VDD1
VDD2
2.5 V
Internal power and ground generated by internal regulator. These also
allow an external source to supply the core VDD/VSS voltages and bypass
the internal voltage regulator.
In the 48 and 52 LQFP packages VDD2 and VSS2 are not available.
