Ram Bal said:
are there any documented best practices for coding? Yes - there is an appendix all about it at the end of the Keil C51 Manual: http://www.keil.com/support/m...c51_xc.htm Also best practices for assigning data, pdata and xdata to various memory and functions to obtain optimal code size? The thing to remember is that accessing DATA takes the least code; then IDATA; then PDATA; then XDATA. Obviously, your most-used variables should be in the most "economical" memory space... |
