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 10 ns input .
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 10 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
I2S-bus specification.
R — Function reserved.
R — Function reserved.
R — Function reserved.
LCD_CLKIN — LCD clock.
P2[12] — General purpose digital input/output pin. This pin
includes a 10 ns input glitch filter.
EINT2 — External interrupt 2 input.
SD_DAT[2] — Data line 2 for SD card interface.
I2S_TX_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.
LCD_VD[4] — LCD data.
LCD_VD[3] — LCD data.
LCD_VD[8] — LCD data.
LCD_VD[18] — LCD data.
