 Arbitrary LPC (low pin count) traffic
 -------------------------------------------------------------------------------
 
-These captures are the identification and programming with random data of a LPC
-(low pin count) interface flash chip. The LPC bus is emulated with an ARM
-Cortex-M microcontroller, and does not run at the standard 33MHz clock. Although
-the clock contains significant jitter, the connected chips respond and
-communicate as expected.
