SPECIFIC REGISTERS
IDENTIFICATION
The MC13892 parts can be identified though identification bits which are hardwired on chip.
The version of the MC13892 can be identified by the ICID[2:0] bits. This is used to distinguish future derivatives or
customizations of the MC13892. The bits are set to ICID[2:0] = 111 and are located in the revision register.
The revision of the MC13892 is tracked with the revision identification bits REV[4:0]. The bits REV[4:3] track the full mask set
revision, where bits REV[2:0] track the metal revisions. These bits are hardwired.

IC Revision
Pass 3.1
The bits FIN[3:0] are Freescale use only and are not to be explored by the application.
The MC13892 die is produced using different wafer fabrication plants. The plants can be identified via the FAB[1:0] bits. These
bits are hardwired.
MEMORY REGISTERS
The MC13892 has a small general purpose embedded memory of two times 24-bits to store critical data. The data is
maintained when the device is turned off and when in a power cut. The contents are only reset when a RTC reset occurs, see
