P1_7
R5 N3 J4 65 48 [2] N; PU I/O GPIO1[8] — General purpose digital input/output pin.
O CTOUT_10 — SCT output 10. Match output 3 of
timer 3.
- R — Function reserved.
O EMC_CS0 — LOW active Chip Select 0 signal.
I 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).
I/O SSP1_SSEL — Slave Select for SSP1.
- R — Function reserved.
O SD_POW — SD/MMC card power monitor output.
T4 P3 K4 67 49 [2] N; PU I/O GPIO1[9] — General purpose digital input/output pin.
I CTIN_5 — SCT input 5. Capture input 2 of timer 2.
- R — Function reserved.
O EMC_WE — LOW active Write Enable signal.
- R — Function reserved.
- R — Function reserved.
- R — Function reserved.
I/O SD_CMD — SD/MMC command signal.
T5 N4 G4 69 50 [2] N; PU I/O GPIO1[0] — General purpose digital input/output pin.
I U1_DSR — Data Set Ready input for UART1.
O CTOUT_13 — SCT output 13. Match output 3 of
timer 3.
I/O EMC_D0 — External memory data line 0.
O 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.
