P1[29] — General purpose digital input/output pin.
USB_SDA1 — USB port 1 I2C serial data (OTG transceiver).
PWM1_CAP1 — Capture input for PWM1, channel 1.
T0_MAT1 — Match output for Timer 0, channel 1.
MC_2B — Motor control PWM channel 2, output B.
U4_TXD — Transmitter output for USART4 (input/output in
smart card mode).
LCD_VD[15] — LCD data.
LCD_VD[23] — LCD data.
P1[30] — General purpose digital input/output pin.
USB_PWRD2 — Power Status for USB port 2.
USB_VBUS — Monitors the presence of USB bus power.
This signal must be HIGH for USB reset to occur.
ADC0_IN[4] — A/D converter 0, input 4. When configured as an
ADC input, the digital function of the pin must be disabled.
I2C0_SDA — I2C0 data input/output (this pin does not use a
specialized I2C pad).
U3_OE — RS-485/EIA-485 output enable signal for UART3.
P1[31] — General purpose digital input/output pin.
USB_OVRCR2 — Over-Current status for USB port 2.
SSP1_SCK — Serial Clock for SSP1.
ADC0_IN[5] — A/D converter 0, input 5. When configured as an
ADC input, the digital function of the pin must be disabled.
I2C0_SCL — I2C0 clock input/output (this pin does not use a
specialized I2C pad).
Port 2: Port 2 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.
P2[0] — General purpose digital input/output pin.
PWM1[1] — Pulse Width Modulator 1, channel 1 output.
U1_TXD — Transmitter output for UART1.
