P2[9] 132 H16 H11 92
[3]
I;
PU
I/O P2[9] — General purpose digital input/output pin.
O 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.
I U2_RXD — Receiver input for UART2.
I U4_RXD — Receiver input for USART4.
I/O ENET_MDIO — Ethernet MIIM data input and output.
- R — Function reserved.
I LCD_VD[3] — LCD data.
I LCD_VD[7] — LCD data.
P2[10] 110 N15 M13 76
[10]
I;
PU
I/O 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.
I EINT0
— External interrupt 0 input.
I NMI — Non-maskable interrupt input.
P2[11] 108 T17 M12 75
[10]
I;
PU
I/O P2[11] — General purpose digital input/output pin. This pin
includes a 10 ns input glitch filter.
I EINT1
— External interrupt 1 input.
I/O SD_DAT[1] — Data line 1 for SD card interface.
I/O I2S_TX_SCK — Transmit Clock. It is driven by the master and
received by the slave. Corresponds to the signal SCK in the
I
2
S-bus specification.
- R — Function reserved.
- R — Function reserved.
- R — Function reserved.
O LCD_CLKIN — LCD clock.
P2[12] 106 N14 N14 73
[10]
I;
PU
I/O P2[12] — General purpose digital input/output pin. This pin
includes a 10 ns input glitch filter.
I EINT2
— External interrupt 2 input.
I/O SD_DAT[2] — Data line 2 for SD card interface.
I/O I2S_TX_WS — Transmit Word Select. It is driven by the master
and received by the slave. Corresponds to the signal WS in the
I
2
S-bus specification.
O LCD_VD[4] — LCD data.
O LCD_VD[3] — LCD data.
O LCD_VD[8] — LCD data.
O LCD_VD[18] — LCD data.
