Section 5 Resets and Interrupts
5.1 Overview
Consult the Exception Processing section of the HCS12 Core User Guide for information on resets and
interrupts. Both local masking and CCR masking are included as listed in Table 5-1. System resets can
be generated through external control of the RESET pin, through the clock and reset generator module
CRG_U. Refer to the CRG_U User Guide for detailed information on reset generation.
5.2 Vectors
5.2.1 Vector Table
Table 5-1 lists interrupt sources and vectors in default order of priority.
