LPC178x/7x
32-bit ARM Cortex-M3 microcontroller
P0[13] 45 R2 J5 32
[5]
I;
PU
I/O P0[13] — General purpose digital input/output pin.
O USB_UP_LED2 — USB port 2 GoodLink LED indicator. It is
LOW when the device is configured (non-control endpoints
enabled), or when the host is enabled and has detected a
device on the bus. It is HIGH when the device is not configured,
or when host is enabled and has not detected a device on the
bus, or during global suspend. It transitions between LOW and
HIGH (flashes) when the host is enabled and detects activity on
the bus.
I/O SSP1_MOSI — Master Out Slave In for SSP1.
I ADC0_IN[7] — A/D converter 0, input 7. When configured as an
ADC input, the digital function of the pin must be disabled.

O USB_HSTEN2
— Host Enabled status for USB port 2.
I/O SSP1_SSEL — Slave Select for SSP1.
O USB_CONNECT2 — SoftConnect control for USB port 2.
Signal used to switch an external 1.5 k resistor under software
control. Used with the SoftConnect USB feature.
