High-speed CAN/LIN fail-safe system basis chip
6.13.11
General purpose registers and general purpose feedback registers
The UJA1065 offers two 12-bit General Purpose registers (and accompanying General
Purpose Feedback registers) with no predefined bit definition. These registers can be
used by the microcontroller for advanced system diagnosis, or for storing critical system
status information outside the microcontroller. After Power-up General Purpose register 0
will contain a ‘Device Identification Code’ consisting of the SBC type and SBC version.
This code is available until it is overwritten by the microcontroller (as indicated by the DIC
bit).
[1]
The Device Identification Control bit is cleared during power-up of the SBC, indicating that General Purpose register 0 is loaded with the
Device Identification Code. Any write access to General Purpose register 0 will set the DIC bit, regardless of the value written to DIC.
[2]
During power-up the General Purpose register 0 is loaded with a ‘Device Identification Code’ consisting of the SBC type and SBC
version, and the DIC bit is cleared.
6.13.12
Register configurations at reset
At Power-on, Start-up and Restart the setting of the SBC registers is predefined. With
external reset events (edge at pin RSTN) the registers will be set as in Start-up mode,
with the exception of the ILEN bit in the System Configuration register.
