while the M2 is in BSL mode. All code fetches to segment 0 are made from the special
Boot-ROM, while data accesses read from the external user ROM.

Identification Registers
A set of 8 identification registers are provided to offer information on the chip as
manufacturer, chip type and its memory (EEPROM, OTP, DRAM or Flash memory)
properties, and information on the CSCU (type of module, redesign state).
The ID registers are read only registers. These registers are:
• IDMANUF, for manufacturer and department identification,
• IDCHIP, for device identification and revision code,
• IDMEM, for identification of on-chip program memory (type, size),
• IDMEM2, for identification of additional EEPROM, OTP, DRAM or Flash memory,
• IDPROG, for identification of programming/erasing voltage of on-chip program
memory,
• IDRT, redesign tracking register for identification of revisions and laser cuts.
Besides, some other registers provide identification of some parts of the M2. These
registers are hardwired inside the M2.
• CPUID, for CPU identification,
• IDSCU, for CSCU identification,
• DIPX version bit field, for OCDS identification.
