One does not check responses during programming at all, gang programming all together, then one verifies each individually. Verification is MUCH faster than programming, can be 200-1000 times faster for 10msec programming pulses, with 1usec/bit readout speeds, therefore this is a majo= r speedup. Most gang programmers use this technique, for pics, mcus, EEPROMs and all that. This is a well known art [r][tm], (patent trolls and other dimwits beware - just in case). -- Peter --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
