I want to use the UICR customer registers to store MAC/serialization information for my devices. It looks like the UICR customer section would be great, and the product spec says they are reserved for user application, but @jldewitt mentioned here that the UICR might be used by the bootloader. Is there any documentation on this? I am using a semi-stock Nordic DFU bootloader, but haven't found any info on possible Customer UICR usage...
