use VLPS and pdb-adc?

[michaelmac]

Hi all, 

is there a way to somehow wake the bus clock for the PDB from the LPTMR, from VLPS, at the same time as using LPTMR for the trig-sel? 

for example, i have the 32k xtal driving the LPTMR. This triggers the PDB, which triggers ADC0 A then B. it works ok in run mode, but i want it to work from VLPS.

im using the FRDM-K22 board. 

thanks,

michael.

Hi Michael Maclean 

This is not possible, because PDB timer doesn't work in VLPS. So evean you LPTMR trigger PDB, this will not work in this mode.

Hope this information help
