CPU1.LINK1
is
primarily used for bootloaders, and has extra hard-coded privileges to support
bootloader functions, such as the ability to write to certain system configuration
registers. LINK1 can also be used as a conventional user LINK; however, adding
non-bootloader-related code and data to LINK1 is not recommended except as a last
resort when all other LINKs are already in use.
When any peripheral boot mode is configured in the Boot Settings group, SysConfig automatically configures LINK1 to have access to the respective peripherals required for that boot mode to function, for example, CAN, UART, or SPI. These peripherals are automatically added to the LINK1 module by SysConfig, in addition to certain peripherals that are always required for device boot, such as IPC and the HSM mailbox.
