SNOOZE mode in RL78/G13

Hi all,

I am working on RL78/G13 controller with internal clock of 1MHz.

No external clock mounted on the board.

Now I want to put the controller into SNOOZE mode and perform ADC operation.

Can someone help me how to do this?

Thanks,

Mouna

Hi Mouna,

When you want to use the ADC in SNOOZE mode, you must set the AWC bit of the ADM2 register to 1 immediately before switching to the STOP mode. Please refer to chapter 18.3.3 and 11.3.4 for more details.

Hi JB,

Yes I am doing that. Thanks for your reply.

But I am stuck at one point.
I am setting 15V as the threshold to generate INTAD interrupt. Even if supply voltage is >15V also, INTAD is not getting generated.

So controller is remaining in STOP mode only.

Can someone help me with this?

Thanks,
Mouna

Hi,

I got solved. It was due to mistake in the configuration of ADM1 register.

Thanks,
