LPC Bus Enhancements

• The LPC interface operates from 24MHz to 33MHz.

• An optional mode is added to the LPC interface that will reduce wait states when operating at 33MHz.

1.11

VCI modifications

• VCI inputs have programmable polarity. See

• Status latches on VCI pins capture rising edges and falling edges. See
