Introduction

This chapter describes the MM912F634 dual die device functions on a block by block base. To distinguish between the module

location being the MCU die or the analog die, the following symbols are shown on all module cover pages:

The documented module is physically located on the Analog die. This applies to Section 4.2, “MM912F634 - Analog

Die Overview" through Section 4.25, “MM912F634 - Analog Die Trimming".

The documented module is physically located on the Microcontroller die. This applies to Section 4.26, “MM912F634

- MCU Die Overview" through Section 4.38, “Serial Peripheral Interface (S12SPIV4)".

Sections concerning both dies or the complete device will not have a specific indication.

Device Register Maps

Table 47 shows the device register memory map overview for the 32 kByte MCU die (MC9S12I32).

NOTE

Reserved register space shown in Table 47 is not allocated to any module. This register

space is reserved for future use, and will show as grayed areas in tables throughout this

document. Writing to these locations has no effect. Read access to these locations returns

zero.
