WebToggling Bits We can also toggle or switch the value of individual bits from 1 to 0 or vice versa. This is done with the XOR function. Remember from the truth table, that an XOR gate is like a programmable inverter. If A is set to zero, B is passed through to the output untouched. If A is set to one, B is inverted at the output. crypto mining rig for sale ebay

By using a mask for operand two, we can test if an individual bit in R0 is set. In this case, we check bit 3 (bitmask = 1000b = 8) and set the Z flag based on the outcome. TEQ performs a similar function to exclusive or and is great for checking whether two registers are equal.
