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.
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.
5.4 Interrupts
For details on the different kind of interrupts refer to the HCS12 Interrupt Block User Guide and according
module Block User Guides.
