Specifications

The XRS pin can be driven externally by a supervisor or an external pullup resistor, see Table 4-1.

After reset from any source (see Section 5.9.2.1), the boot ROM code samples Boot Mode pins. Based on the status

of the Boot Mode pin, the boot code branches to destination memory or boot code function. If boot ROM code

executes after power-on conditions (in debugger environment), the boot code execution time is based on the current

SYSCLK speed. The SYSCLK will be based on user environment and could be with or without PLL enabled.

After reset from any source (see Section 5.9.2.1), the Boot ROM code samples BOOT Mode pins. Based on the

status of the Boot Mode pin, the boot code branches to destination memory or boot code function. If Boot ROM code

executes after power-on conditions (in debugger environment), the Boot code execution time is based on the current

SYSCLK speed. The SYSCLK will be based on user environment and could be with or without PLL enabled.
