Freescale Semiconductor 1265
A.4.1 Chip Power-up and Voltage Drops
MC9S12XDP512 sub modules LVI (low voltage interrupt), POR (power-on reset) and LVR (low voltage
reset) handle chip power-up or drops of the supply voltage.

A.4.2 Output Loads
A.4.2.1 Resistive Loads
On-chip voltage regulator MC9S12XDP512 intended to supply the internal logic and oscillator circuits
allows no external DC loads.
A.4.2.2 Capacitive Loads
The capacitive loads are specified in Table A-20.. Ceramic capacitors with X7R dielectricum are required.
