I/O GPIO1[8] — General purpose digital input/output pin.
O CTOUT_10 — SCTimer/PWM 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.
P1_6 T4 K4 49 67

PU
I/O GPIO1[9] — General purpose digital input/output pin.
I CTIN_5 — SCTimer/PWM input 5. Capture input 2 of timer 2.
- R — Function reserved.
O EMC_WE
LOW active Write Enable signal.
- R — Function reserved.
O EMC_BLS0
LOW active Byte Lane select signal 0.
- R — Function reserved.
I/O SD_CMD — SD/MMC command signal.

PU
I/O GPIO1[0] — General purpose digital input/output pin.
I U1_DSR — Data Set Ready input for UART1.
O CTOUT_13 — SCTimer/PWM 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.
