Resets are a subset of the interrupts featured in
system reset are summarized in
changed to known start-up states. Refer to the respective module Block User Guides for register reset
states.
1.6.2.1
1.6.2.2
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. Refer to the HCS12 Multiplexed External
Bus Interface (MEBI) Block Guide for mode dependent pin configuration of port A, B and E out of reset.
Refer to the PIM Block User Guide for reset configurations of all peripheral module ports.
Refer to
after reset.
The RAM array is not automatically initialized out of reset.

1.7.1
External paging is not supported on these devices. In order to access the 16K flash blocks in the address
range 0x8000–0xBFFF the PPAGE register must be loaded with the corresponding value for this range.
Refer to
For all devices Flash Page 3F is visible in the 0xC000–0xFFFF range if ROMON is set. For all devices
(except MC9S12GC16) Page 3E is also visible in the 0x4000–0x7FFF range if ROMHM is cleared and
ROMON is set. For all devices apart from MC9S12C32 Flash Page 3D is visible in the 0x0000–0x3FFF
range if ROMON is set...

For devices assembled in 48-pin or 52-pin LQFP packages all non-bonded
out pins should be configured as outputs after reset in order to avoid current
drawn from floating inputs. Refer to
