In addition to the t
requirement, XRS has to be low at least for 1 ms after V
DD
reaches 1.5 V.
Dependent on crystal/resonator and board design.
A.
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.
Figure 6-7. Warm Reset
Figure 6-8
shows an example for the effect of writing into PLLCR register. In the first phase, PLLCR =
0x0004 and SYSCLKOUT = OSCCLK x 2. The PLLCR is then written with 0x0008. Right after the PLLCR
register is written, the PLL lock-up phase begins. During this phase, SYSCLKOUT = OSCCLK/2. After the
PLL lock-up is complete (which takes 131072 OSCCLK cycles), SYSCLKOUT reflects the new operating
frequency, OSCCLK x 4.
