Description
P2[8] — General purpose digital input/output pin.
CAN_TD2 — CAN2 transmitter output.
U2_TXD — Transmitter output for UART 2.
U1_CTS — Clear to Send input for UART 1.
ENET_MDC — Ethernet MIIM clock.
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 kΩ resistor under the software control.
Used with the SoftConnect USB feature.
U2_RXD — Receiver input for UART 2.
U4_RXD — Receiver input for UART 4.
ENET_MDIO — Ethernet MIIM data input and output.
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.
Note: 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.
P2[11] — General purpose digital input/output pin. This pin
includes a 5 ns input glitch filter.
EINT1 — External interrupt 1 input.
SD_DAT[1] — Data line 1 for SD card interface.
I2S_TX_SCK — Transmit Clock. It is driven by the master and
received by the slave. Corresponds to the signal SCK in the
I
LCD_CLKIN — LCD clock.
