d = 0: Rd-code encodes G0..G15 for Rd, d = 1: Rd-code encodes L0..L15 for Rd
n: Bit 8 // bits 3..0 encode n = 0..31, see Table 2.3 Encoding of Immediate Values for encoding of imm
Notation:
XORI Rd, imm
Description:
The result of a bitwise exclusive OR (XOR) of the immediate operand (imm) and the
destination operand (Rd) is placed in the destination register (Rd) and the Z flag is set or
cleared accordingly.
All operands and the results are interpreted as bit-stings of 32bits each.
Operation:
Rd := Rd xor imm;
Z := Rd = 0;
Exceptions:
None.
