Chapter 1 Device Overview MC9S12XD-Family
Internal power and ground generated by
internal regulator
External power and ground, supply to pin
drivers and internal voltage regulator
External power and ground, supply to pin
drivers
External power and ground, supply to pin
drivers
External power and ground, supply to pin
drivers
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.
Reference voltages for the analog-to-digital
converter.
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.
