TRACEPKT1 — Trace Packet, bit 1.

P2[7]/RD2/

RTS1/TRACEPKT2

66[1]

I/O

P2[7] — General purpose digital input/output pin.

RD2 — CAN2 receiver input.

RTS1 — Request to Send output for UART1.

TRACEPKT2 — Trace Packet, bit 2.

P2[8]/TD2/

TXD2/TRACEPKT3

65[1]

I/O

P2[8] — General purpose digital input/output pin.

P2[9]/

USB_CONNECT/

RXD2/EXTIN0

64[1]

I/O

P2[9] — General purpose digital input/output pin.

USB_CONNECT — Signal used to switch an external 1.5 k

Ω resistor under

software control. Used with the SoftConnect USB feature.

RXD2 — Receiver input for UART2.

EXTIN0 — External Trigger Input.

P2[10]/EINT0

53[6]

I/O

P2[10] — General purpose digital input/output pin.

Note: LOW on this pin while RESET is LOW forces on-chip bootloader to take

over control of the part after a reset.

EINT0 — External interrupt 0 input.

P2[11]/EINT1/

MCIDAT1/

I2STX_CLK

52[6]

I/O

P2[11] — General purpose digital input/output pin.

EINT1 — External interrupt 1 input.

MCIDAT1 — Data line for SD/MMC interface.

I/O

I2STX_CLK — Transmit Clock. It is driven by the master and received by the

slave. Corresponds to the signal SCK in the

I2S-bus speciﬁcation.

P2[12]/EINT2/

MCIDAT2/

I2STX_WS

51[6]

I/O

P2[12] — General purpose digital input/output pin.

EINT2 — External interrupt 2 input.

MCIDAT2 — Data line for SD/MMC interface.

I/O

I2STX_WS — Transmit Word Select. It is driven by the master and received by

the slave. Corresponds to the signal WS in the

I2S-bus speciﬁcation.

P2[13]/EINT3/

MCIDAT3/

I2STX_SDA

50[6]

I/O

P2[13] — General purpose digital input/output pin.

EINT3 — External interrupt 3 input.

MCIDAT3 — Data line for SD/MMC interface.

I/O

I2STX_SDA — Transmit data. It is driven by the transmitter and read by the

receiver. Corresponds to the signal SD in the

I2S-bus speciﬁcation.

P3[0] to P3[31]

I/O

Port 3: Port 3 is a 32-bit I/O port with individual direction controls for each bit.

The operation of port 3 pins depends upon the pin function selected via the pin

connect block. Pins 0 through 24, and 27 through 31 of this port are not available.

P3[25]/MAT0[0]/

PWM1[2]

27[1]

I/O

P3[25] — General purpose digital input/output pin.

MAT0[0] — Match output for Timer 0, channel 0.

PWM1[2] — Pulse Width Modulator 1, output 2.
