hi,

Raghunathan, probably you are right. It seems that Nitin asks for additional information, like "at which state of machine cycle the register TEMP2 of 8051 core is loaded into ALU?"

Nitin, this document shows State Sequences in Atmel Flash Microcontrollers (pages 2.16 and below). But I think it does not give you more info than you already have. I doubt that such information you asked about, is published somewhere. Try to search Internet, maybe try to ask Intel tech for it.

Regards,
Oleg
