5.3 Resets
Resets are a subset of the interrupts featured inTable 5-1. The different sources capable of generating a
system reset are summarized in Table 5-2.
5.3.1 Reset Summary Table
5.3.2 Effects of Reset
When a reset occurs, MCU registers and control bits are changed to known start-up states. Refer to the
respective module Block Guides for register reset states. Refer to the HCS12 Core User Guides for mode
dependent pin configuration of port A, B and E out of reset.
Refer to the PIM Block Guide for reset configurations of all peripheral module ports.
Refer to for location of the memories depending on the operating mode after reset.
The RAM array is not automatically initialized out of reset.
