I use NMI on the wakeup pin.

Can I use the wakeup pin to wake up from deep-sleep mode using the NMI hadler ?

Regards

In short:

Can NMI exception wake the mcu from DEEPSLEEP mode ?

Hello !
In which state (pull up/down, high impedance) are GPIO pins during a Deep-Sleep in LPC11C14 ? Is it configurable ?

Yes it is configurable.
I experiment much to achieve the lowest consumption

I want ask about an issue on exceptions on lpc11xx(XL).

On a project that uses deep-sleep and power-down mode which exception to use ?

In deep-sleep, wakeup handler and reset can be used (nmi doesn't respond),
In power-down, the wakeup pin can be used (reset doesn't respond),
In normal mode, the nmi handler and reset can be used.

While in power-down mode, the wakeup pin must be used as nmi but you can't have control in deep-sleep mode.
While in deep-sleep mode, the wakeup handler pin (start logic STARTAPRP) must be used but you can't have control in power-down mode.

I can only think about hardwire the wakeup pin with a wakeup handler (or reset) pin in a wired-OR connection.

Am I missing something ?
Is there any proposed solution on such issues ?

Regards,
Theodore
