Description
EMC_CKEOUT1 — SDRAM clock enable 1.
USART0.
read by the receiver. Corresponds to the signal SD in the I
specification.
R — Function reserved.
T2_CAP1 — Capture input 1 of timer 2.
R — Function reserved.
R — Function reserved.
USB0_PPWR — VBUS drive signal (towards external charge pump or
power management unit); indicates that VBUS 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.
