Using the NAND Flash interface prevents:
Using the CompactFlash interface prevents:
As the DataFlash Card is compatible with the SDCard, it is useful to multiplex SPI and MCI.
Here, the SPI0 signal is multiplexed with the MCI.
• using the three Timer Counter channels’ outputs and trigger inputs
• using the SSC2
• using NCS3, NCS6 and NCS7 to access other parallel devices
• using NCS4 and/or NCS5 to access other parallel devices
• Using the USART1 and USART2 control signals prevents using the ETM.
• Alternatively, using USART0 with its control signals prevents using some clock outputs and
• Using the clock outputs multiplexed with the PIO A prevents using the Debug Unit and/or the
• Alternatively, using the second implementation of the clock outputs prevents using the LCD
• Using FIQ prevents using the USART0 control signals.
• Using IRQ0 prevents using the NWAIT EBI signal.
• Using the IRQ1 and/or IRQ2 prevents using the SPI1.
