* The switch to 16x averaging is done to combat the excessive noise in the signal. It's still *very* bad, but the TS cursor jitter has decreased a bit * The OPP for 275MHz was disabled due to all the errata. Both the EMIF and MUSB don't seem to like that OPP. * The resistive touch version of the 4.3" LCD cape is supported in 24 bit mode.
