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 Core User Guides 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.
NOTE:
For devices assembled in 80-pin QFP packages all non-bonded out pins should be
configured as outputs after reset in order to avoid current drawn from floating
inputs. Refer to
Table 2-1
for affected pins.
5.3.2 Memory
Refer to
Table 1-1
for locations of the memories depending on the operating mode after reset.
The RAM array is not automatically initialized out of reset.
