A.
Upon power up, SYSCLKOUT is OSCCLK/2. Since the XCLKOUTDIV bits in the XCLK register come up with a reset
state of 0, SYSCLKOUT is further divided by 4 before it appears at XCLKOUT. This explains why XCLKOUT =
OSCCLK/8 during this phase.
After reset, 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 SYSCLKOUT speed. The SYSCLKOUT
will be based on user environment and could be with or without PLL enabled.
