Description
CTOUT_10 — SCT output 10. Match output 2 of timer 2.
R — Function reserved.
EMC_CS0 — LOW active Chip Select 0 signal.
USB0_PWR_FAULT — Port power fault signal indicating overcurrent
condition; this signal monitors over-current on the USB bus (external
circuitry required to detect over-current condition).
R — Function reserved.
SD_POW — <tbd>.
CTIN_5 — SCT input 5. Capture input 2 of timer 2.
R — Function reserved.
EMC_WE — LOW active Write Enable signal.
R — Function reserved.
EMC_BLS0 — LOW active Byte Lane select signal 0.
R — Function reserved.
U1_DSR — Data Set Ready input for UART1.
CTOUT_13 — SCT output 13. Match output 1 of timer 3.
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.
