Shadow memory in the HD8 is implemented using main FLASH memory. Endurance is 10,000 writes or clears in total. ShadowWrite takes up to 20mS per byteShadowClear takes up to 10mS per byteDuring these times the SPLat processor can do nothing else (for example quadrature counting). We use a smart algorithm to avoid redundant writes and clears, making the process as fast as possible and reducing wear on the memory.

ShadowRead is very fast.

Downloading a program to the controller does not change the contents of shadow memory.
