SPI0 and the MultiMedia Card Interface
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.
USARTs
• Using USART0 with its control signals prevents using some clock outputs and interrupt lines.
Clock Outputs
• Using the clock outputs multiplexed with the PIO A prevents using the Debug Unit and/or the
Two Wire Interface.
• Alternatively, using the second implementation of the clock outputs prevents using the LCD
Controller Interface and/or USART0.
Interrupt Lines
• 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.
