In the low power AN10915 pdf it says "When the chip enters the Deep Sleep mode, the main oscillator is powered down, and nearly all clocks are stopped."
I need to use two internal timers as counters that will still count when in Deep-sleep mode.
Is this possible?
I could not get it to work.
The counters do work in regular sleep mode.
I leave the power active in the timers in both modes and just replace CLKPWR_Sleep(); with CLKPWR_DeepSleep(); and the other way around.

I understand that the internal oscillator remains running so I do not see why they do not count 1 count a second.

Any help would be appreciated.
