MCF51JM128 quartz in STOP mode

Hello,

I would like to get an information about the quartz in STOP mode.

We encounter a problem at this time. When we put the µC in STOP mode, the quartz continue to oscillate, do you have an idea ?

Our procedure is the following:

1- We received an IT from our other IC (PSOC) to enter in STOP mode

2- We switch off the power supply (5V) ==> to be supplied with the battery (3,7V)

3- We put the PSOC in Low Power Mode (with impulsion time determined by a loop)

4- We configure all the IO in "sleep mode"

5- We reset the IRQ flag

6- We reset the interrupt RTC flag then we disable this one

7- We enter in STOP mode

Thanks in advance

Sébastien
