LPC408x/7x
32-bit ARM Cortex-M4 microcontroller
P2[9] 132 H16 H11 92 64 49 E10
[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 53 41 H9
[10]
I; PU I/O P2[10] — General purpose digital input/output pin. This
pin includes a 10 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.
I EINT0
— External interrupt 0 input.
I NMI — Non-maskable interrupt input.
P2[11] 108 T17 M12 75 52 - -
[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.
