LPC435x/3x/2x/1x
32-bit ARM Cortex-M4/M0 microcontroller
WAKEUP0 A9 A4 187 130
[11]
I; IA I External wake-up input; can raise an interrupt and can cause
wake-up from any of the low power modes. A pulse with a
duration of at least 45 ns wakes up the part.
Input 0 of the event monitor.No internal pull-up is enabled
when this pin is configured as input.
WAKEUP1 A10 - - -
[11]
I; IA I External wake-up input; can raise an interrupt and can cause
wake-up from any of the low power modes. A pulse with a
duration of at least 45 ns wakes up the part.
Input 1 of the event monitor. No internal pull-up is enabled
when this pin is configured as input.
WAKEUP2 C9 - - -
[11]
I; IA I External wake-up input; can raise an interrupt and can cause
wake-up from any of the low power modes. A pulse with a
duration of at least 45 ns wakes up the part.
Input 2 of the event monitor. This pin does not have an internal
pull-up.
WAKEUP3 D8 - - -
[11]
I; IA I External wake-up input; can raise an interrupt and can cause
wake-up from any of the low power modes. A pulse with a
duration of at least 45 ns wakes up the part. This pin does not
have an internal pull-up.
