32-bit ARM Cortex-M0 microcontroller
PIO0_16/AD5/
CT32B1_MAT3/IOH_8/
WAKEUP
26 26 40 53
[6]
I; PU I/O PIO0_16 — General purpose digital input/output
pin.
-IAD5 — A/D converter, input 5.
-OCT32B1_MAT3 — Match output 3 for 32-bit timer
1.
-I/OIOH_8 — I/O Handler input/output 8.
LPC11E37HFBD64/401 only.
-IWAKEUP — Deep power-down mode wake-up
pin with 20 ns glitch filter. Pull this pin HIGH
externally before entering Deep power-down
mode, then pull LOW to exit Deep power-down
mode. A LOW-going pulse as short as 50 ns
wakes up the part.
