Detailed Register Map
The detailed register map is listed in Appendix A.
1.1.7
Part ID Assignments
The part ID is located in two 8-bit registers PARTIDH and PARTIDL (addresses 0x001A and 0x001B).
The read-only value is a unique part ID for each revision of the chip.
Table 1-6
shows the assigned part ID
number and Mask Set number.
The Version ID is a word located in a flash information row at 0x40_00E8. The version ID number
indicates a specific version of internal NVM variables used to patch NVM errata.
The default is no patch (0xFFFF).

Signal Description
This section describes signals that connect off-chip. It includes a pinout diagram, a table of signal
properties, and detailed discussion of signals. It is built from the signal description sections of the Block
User Guides of the individual IP blocks on the device.
1.2.1
Device Pinout
The XE-Family of devices offers pin-compatible packaged devices to assist with system development and
accommodate expansion of the application.
The MC9S12XE-Family devices are offered in the following package options:
208-pin MAPBGA package with an external bus interface (address/data bus)
144-pin LQFP package with an external bus interface (address/data bus)
112-pin LQFP without external bus interface
80-pin QFP without external bus interface
