E.2 MPC555 / MPC556 Family Power Distribution
MPC555 / MPC556
USER’S MANUAL
NOTE 1: The main power supply may
optionally supply operating current to reduce
the keep alive current requirements.
See the circuit in
8.12.1 System Clock Control Register (SCCR)
NOTE 2: Resistor R
Space should be left on the board to add it
in the future if necessary.
