Table 19 LPC/GPIO Signal Descriptions
Signal Pin # Description
LPC_AD0 185 Multiplexed Command, Address and Data (LPC_AD[0..3]).
GPIO0 Shared with General Purpose Input/Output [0..3]
LPC_AD1 186
GPIO1
LPC_AD2 187
GPIO2
LPC_AD3 188
GPIO3
LPC_FRAME# 190 LPC frame indicates the start of a new cycle or the termination
GPIO5 of a broken cycle. Shared with General Purpose Input/Output 5
LPC_LDRQ# 192 LPC DMA request.
GPIO7 General Purpose Input/Output 7
LPC_CLK 189 LPC clock.
GPIO4 General Purpose Input/Output 4
SERIRQ 191 Serialized Interrupt.
GPIO6 General Purpose Input/Output 6
Note
The eight LPC pins are configured by default as GPIO's. Additional eight GPIO pins can be achieved by configuring SDIO pins as GPIO. This
can be programmed in the bootloader and in the kernel.
The conga-QMX6 does not support LPC interface.
Table 20 SPI Interface Signal Descriptions
Signal Pin # Description
SPI_MOSI 199 Master serial output/Slave serial input signal. SPI serial output data from
Qseven ® module to the SPI device.
SPI_MISO 201 Master serial input/Slave serial output signal. SPI serial input data from the SPI
device to Qseven
SPI_SCK 203 SPI clock output.
SPI_CS0# 200 SPI chip select 0 output.
SPI_CS1# 202 SPI Chip Select 1 signal is used as the second chip select when two devices are
used. Do not use when only one SPI device is used.
