Peripheral/GPIO Function

† After reset, the Boot ROM code executes instructions for 1260 SYSCLKOUT cycles (SYSCLKOUT = XCLKIN/2) and then samples BOOT

Mode pins. Based on the status of the Boot Mode pin, the boot code branches to destination memory or boot code function in ROM. The

BOOT Mode pins should be held high/low for at least 2520 XCLKIN cycles from boot ROM execution time for proper selection of Boot

modes.

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

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