5.3 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 User Guides for register reset states.

5.3.1 I/O pins

Refer to the HCS12 Multiplexed External Bus Interface (MEBI) Block Guide for mode dependent pin

configuration of port A, B, E and K out of reset.

Refer to the PIM Block User Guide for reset configurations of all peripheral module ports.
