I am working on a low power design and did some test with the EVK1100 kit. Here are some results:
Kit switched on, init GPIO (light a LED): 1 ms
Kit on, init osc0 at 12 MHz, then GPIO: 2 ms
Kit on, init osc0, init PLL0 to 48 MHz then GPIO: 2.5 ms
This was actually better than expected, especially regarding the PLL setup. The test program is written in assembly.
Wakeup from sleep:
48 MHz, time to wakeup from static sleep by NMI external interrupt: 400 us
