Chip Power Up and Voltage Drops
The VREG 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. Refer to Figure 2.

3.7.6
Output Loads
The on-chip voltage regulator is intended to supply the internal logic and oscillator circuits. No external
DC load is allowed. Capacitive loads are specified in Table 18. Capacitors with X7R dielectricum are
required.

NOTES:
1. Refer to Table 38 for the specific number of VDD2.5 pins on various packages. Each VDD2.5 pin should have the
recommended loading as described in Section 3.7.3, “Circuit Board Layout,” of the MAC7100 Microcontroller Family
Reference Manual (MAC7100RM).
