2.3.4 Configurable Chip Select Pins

By default, the LCD Chip Select and SDCard Chip Select pins are connected on the J1 BoosterPack header to maintain backwards compatibility with existing software that was developed on the old 430BOOST-SHARP96 and the Card Reader SDCard BoosterPack plug-in module.

However, to provide compatibility with the BoosterPack plug-in module pinout standard, 0-Ω resistors R14 and R16 can be removed, while R15 and R17 can be shorted, to switch the chip select pins from J1 to J2 to conform to the BoosterPack plug-in module standard.
