To toggle bits between 0 and 1. Can be used to swap two variables without a temporary variable. Why to Use: Useful for flipping specific bits, performing parity checks, or detecting bitwise changes. Example: Bitwise XOR compares two numbers bit by bit, and the result is 1 if the bits di...
Toggling a Bit:You can use the bitwise XOR operator (^) to toggle a specific bit (change 0 to 1 or 1 to 0). Syntax: // Toggle the nth bit (indexing from right, starting at 0) unsigned int mask = 1 << n; num ^= mask; // Toggle the nth bit ...
We can use the above mask and the bitwisexoroperator to complement (toggle) a bit at Positionpwithout affecting the other bits as 1 num ^ = 1 << p;/* complement bit at position p */ To reset a bit at positionpwithout affecting the other bits in a given number num, we need to ...
Bitwise operators perform the given operation on each bit in the operand. Binary means the operator operates on two operands and unary means the operator operates on a single operand. Toggling a bit and leaving all other bits unchangedx = x ^ mask; (or shorthand x ^= mask;) Bits that ...
Now we have reached the last section of bitwise operators. Bit shift Operators are used when you want to specify the bit number to be changed rather than masking it. If a particular bit has to be set, then we can use left-shift (<<) operator. ...

sets bits 4-7 and clears bits 0-3 of Port 1. You may use the bitwise operators AND(&), OR(|) and XOR(^) to change individual bits of the PORTx VTREGs. For example:PORT1L |= 0x01; /* Set P1L.0 Pin */ PORT0H &= ~0x02; /* Clr P0H.1 Pin */ PORT0L ^= 0x80; /...
PORT8 to obtain the value corresponding to the set pins of Port 8. You may also change the input values of port pins by changing the value of the VTREG. For example, PORT7=0x00F0 sets bits 4-7 and clears bits 0-3 and 8-15. You may use the bitwise operators AND(&), OR(|) ...
