I/O

GPIO3[2] — General purpose digital input/output pin.

USB0_PPWR — VBUS drive signal (towards external

charge pump or power management unit); indicates that

the VBUS signal must be driven (active HIGH).

Add a pull-down resistor to disable the power switch at

reset. This signal has opposite polarity compared to the

USB_PPWR used on other NXP LPC parts.

I/O

SGPIO4 — General purpose digital input/output pin.

EMC_CS1 — LOW active Chip Select 1 signal.

R — Function reserved.

T2_CAP2 — Capture input 2 of timer 2.

R — Function reserved.
