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.
