Problem with timer in low power mode

Hello ,


I am working with KL25Z freedom board.

I run the code for wake up from LLS mode using wakeup timer component from the component library library and its working.

I set the config 0 = PEE and Config 1=BLPI mode .

I need to run the code on config 1 (BLPI mode) and 0 both.

I set the configuration so that when i wakeup from LLS mode it should remain into config 1 means VLPR mode only.


Now when i wakeup from LLS and i am in VLPR mode i need nother timer for sending the data on UART after timer expire.

It seems that i m not able to use LPTMR timer as it is already used by wakeup timer component.

alo not able use in config1 setting.


1) Is it true that i cant use LPTMR again?


and if i am using some other timer TPM0 and in setting i enabled config 0 and 1 for TPM0.

I m not able to set the counter frequency and the overrun period as shown in the attachment.

2) How can i use other timer in VLPR mode?
