Description
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.
Note: 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 — I
specialized I
U3_OE — RS-485/EIA-485 output enable signal for UART 3.
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 — I
specialized I
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 UART 1.
LCD_PWR — LCD panel power enable.
P2[1] — General purpose digital input/output pin.
PWM1[2] — Pulse Width Modulator 1, channel 2 output.
U1_RXD — Receiver input for UART 1.
LCD_LE — Line end signal.
P2[2] — General purpose digital input/output pin.
PWM1[3] — Pulse Width Modulator 1, channel 3 output.
U1_CTS — Clear to Send input for UART 1.
T2_MAT3 — Match output for Timer 2, channel 3.
TRACEDATA[3] — Trace data, bit 3.
LCD_DCLK — LCD panel clock.
