In-System Programming Button

TracNav(TOC)

When held down on power up, the ISP button will enable the built in LPC2106 bootloader.
After the processor has started up, the button can be read as normal GPIO. It is internally
pulled high, and set low when depressed. The button shares the CS pin (P0.14) with the MMC.
When using the MMC, CS is active low and hence the button cannot adversely affect data
transfers.
