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

CAN_RD2 — CAN2 receiver input.

U1_RTS — Request to Send output for UART1. Can also be

configured to be an RS-485/EIA-485 output enable signal for

UART1.

R — Function reserved.

R — Function reserved.

R — Function reserved.

LCD_VD[1] — LCD data.

LCD_VD[5] — LCD data.

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

CAN_TD2 — CAN2 transmitter output.

U2_TXD — Transmitter output for UART2.

U1_CTS — Clear to Send input for UART1.

ENET_MDC — Ethernet MIIM clock.

R — Function reserved.

LCD_VD[2] — LCD data.

LCD_VD[6] — LCD data.

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

USB_CONNECT1 — USB1 SoftConnect control. Signal used to

switch an external 1.5 k resistor under the software control.

Used with the SoftConnect USB feature.

U2_RXD — Receiver input for UART2.

U4_RXD — Receiver input for USART4.

ENET_MDIO — Ethernet MIIM data input and output.

R — Function reserved.

LCD_VD[3] — LCD data.

LCD_VD[7] — LCD data.

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

includes a 5 ns input glitch filter.

A LOW on this pin while RESET is LOW forces the on-chip boot

loader to take over control of the part after a reset and go into

ISP mode.

EINT0 — External interrupt 0 input.

NMI — Non-maskable interrupt input.
