RESET:
1. Operates as MODCK[1] during reset.
2. This holds if MTSC bit is reset to 0. Otherwise IRQ[2]/CR/SGPIOC[2]/MTS will function as MTS.
The internal memory map register (IMMR) is a special register located within the
MPC555 / MPC556 special register space. The IMMR contains identification of a spe-
cific device as well as the base for the internal memory map. Based on the value read
from this register, software can deduce availability and location of any on-chip system
resources.
This register can be read by the mfspr instruction. The ISB field can be written by the
mtspr instruction. The PARTNUM and MASKNUM fields are mask programmed and
cannot be changed.
* The reset value is a reset configuration word value extracted from the indicated bits of the internal data bus. Refer
