Description
P0[25] — General purpose digital input/output pin.
ADC0_IN[2] — A/D converter 0, input 2. When configured as an
ADC input, the digital function of the pin must be disabled.
I2S_RX_SDA — Receive data. It is driven by the transmitter and
read by the receiver. Corresponds to the signal SD in the I
specification.
U3_TXD — Transmitter output for UART 3.
P0[26] — General purpose digital input/output pin.
ADC0_IN[3] — A/D converter 0, input 3. When configured as an
ADC input, the digital function of the pin must be disabled.
DAC_OUT — D/A converter output. When configured as the DAC
output, the digital function of the pin must be disabled.
U3_RXD — Receiver input for UART 3.
P0[27] — General purpose digital input/output pin.

P0[29] — General purpose digital input/output pin.
USB_D+1 — USB port 1 bidirectional D+ line.
EINT_0 — External interrupt 0 input.
P0[30] — General purpose digital input/output pin.
USB_D−1 — USB port 1 bidirectional D− line.
EINT_1 — External interrupt 1 input.
P0[31] — General purpose digital input/output pin.
USB_D+2 — USB port 2 bidirectional D+ line.
Port 1: Port 1 is a 32 bit I/O port with individual direction controls
for each bit. The operation of port 1 pins depends upon the pin
function selected via the pin connect block
P1[0] — General purpose digital input/output pin.
ENET_TXD0 — Ethernet transmit data 0 (RMII/MII interface).
T3_CAP1 — Capture input for Timer 3, channel 1.
SSP2_SCK — Serial clock for SSP2.
