Chapter 14: LPC43xx Pin configuration
P6_1 R15 P14 107
[3]
N;
PU I/O GPIO3[0] — General purpose digital input/output pin.
O EMC_DYCS1 — SDRAM chip select 1.
I/O U0_UCLK — Serial clock input/output for USART0 in synchronous
mode.
I/O I2S0_RX_WS — Receive 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 .
- R — Function reserved.
I T2_CAP0 — Capture input 2 of timer 2.
- R — Function reserved.
- R — Function reserved.
P6_2 L13 K11 111
[3]
N;
PU I/O GPIO3[1] — General purpose digital input/output pin.
O EMC_CKEOUT1 — SDRAM clock enable 1.
I/O U0_DIR — RS-485/EIA-485 output enable/direction control for
USART0.
I/O I2S0_RX_SDA — I2S Receive data. It is driven by the transmitter
and read by the receiver. Corresponds to the signal SD in the I
2
S-bus
specification .
- R — Function reserved.
I T2_CAP1 — Capture input 1 of timer 2.
- R — Function reserved.
- R — Function reserved.
P6_3 P15 N13 113
[3]
N;
PU I/O GPIO3[2] — General purpose digital input/output pin.
O USB0_PPWR — VBUS drive signal (towards external charge pump
or power management unit); indicates that the VBUS signal must be
driven (active HIGH).
Add a pull-down resistor to disable the power switch at reset. This
signal has opposite polarity compared to the USB_PPWR used on
other NXP LPC parts.
I/O SGPIO4 — General purpose digital input/output pin.
O EMC_CS1 — LOW active Chip Select 1 signal.
- R — Function reserved.
I T2_CAP2 — Capture input 2 of timer 2.
- R — Function reserved.
- R — Function reserved.
