It has 8 bytes, but each byte is repeated 8 * times so the processor can fetch it out of flash whether the flash * is 8, 16, 32, or 64 bits wide (hardware trickery). */ This does _not_ hold true for all configurations. Flash is simply one of many options ... Maybe it's true for the Freescale boards. Other sources of the HRCW can be hard-coded strapping pins or an I2C EEPROM. Why is there a need to define the HRCW ? regards, Andre Schwarz Matrix Vision MATRIX VISION GmbH, Talstra?e 16, DE-71570 Oppenweiler - Registergericht: Amtsgericht Stuttgart, HRB 271090 Gesch?ftsf?hrer: Gerhard Thullner, Werner Armingeon, Uwe Furtner
