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:
ORI Rd, imm
Description:
The result of a bitwise logical OR of the immediate operand and the destination operand is
placed in the destination register and the Z flag is set or cleared accordingly.
All operands and the result are interpreted as bit-strings of 32 bits each.
Operation:
Rs := Rd or imm;
Z := Rd = 0;
Exceptions:
None.
