The 8051 Instruction set is defined in chapter 2 of the "bible:"
Chapter 2 - 80C51 Family Programmer's Guide and Instruction Set: http://www.semiconductors.philips.com/acrobat/v...UIDE_1.pdf There is no specific "greater than" or "less than" instruction - rather, you do a subtraction and test the Carry flag... There are "is zero" and "not equal to" instructions... For your info, the other 2 key chapters of the "bible" are: Chapter 1 - 80C51 Family Architecture: http://www.semiconductors.philips.com/acrobat/v...ARCH_1.pdf Chapter 3 - 80C51 Family Hardware Description: http://www.semiconductors.philips.com/acrobat/v...WARE_1.pdf |
