This article from Keil's support knowledge database shows that one can directly write to ACC from C51 code. http://www.keil.com/support/docs/1619.htm I would like to know if there are any rules when writing to ACC from C code. I have noticed that the following line in my code was entirely commented out when I chose Code Optimization Level-9.
unsigned char data uDataIndex, uDataArray[5]; void main() { . . ACC=uDataArray[uDataIndex%5]; . }
