I; IA I/O

P0[8] — General purpose digital input/output pin.

I/O

I2S_TX_WS — I2S Transmit word select. It is driven by the

master and received by the slave. Corresponds to the signal WS

in the I2S-bus specification.

I/O

SSP1_MISO — Master In Slave Out for SSP1.

T2_MAT2 — Match output for Timer 2, channel 2.

RTC_EV1 — Event input 1 to Event Monitor/Recorder.

R — Function reserved.

LCD_VD[16] — LCD data.

I; IA I/O

P0[9] — General purpose digital input/output pin.

I/O

I2S_TX_SDA — I2S transmit data. It is driven by the transmitter

and read by the receiver. Corresponds to the signal SD in the

I2S-bus specification.

I/O

SSP1_MOSI — Master Out Slave In for SSP1.

T2_MAT3 — Match output for Timer 2, channel 3.

RTC_EV2 — Event input 2 to Event Monitor/Recorder.

R — Function reserved.

LCD_VD[17] — LCD data.

R14

P12

[3]

I/O

P0[11] — General purpose digital input/output pin.

U2_RXD — Receiver input for UART2.

I/O

I2C2_SCL — I2C2 clock input/output (this pin does not use a

specialized I2C pad).

T3_MAT1 — Match output for Timer 3, channel 1.

P0[12]

[5]

I/O

P0[12] — General purpose digital input/output pin.

USB_PPWR2 — Port Power enable signal for USB port 2.

I/O

SSP1_MISO — Master In Slave Out for SSP1.

ADC0_IN[6] — A/D converter 0, input 6. When configured as an

ADC input, the digital function of the pin must be disabled.
