Read modify write ddr
WebREAD-MODIFY-WRITE refers to the technique used to implement an assembly instruction and is typically used by the bitwise operations (AND, OR, XOR). For example, the following instruction: ORL P1,#01h. reads the value of the P1 latch (not the input pins), modifys the value read--it performs a bitwise OR (with 0x01)--, and writes the new value ...
