The SH-3 has a very limited number of read-modify-write operations. To recap: AND.B #imm, @(r0, GBR) ; @(r0 + gbr) &= 8-bit immediate OR.B #imm, @(r0, GBR) ; @(r0 + gbr) |= 8-bit immediate XOR.B #imm, @(r0, GBR) ; @(r0 + gbr) ^= 8-bit immediate TAS.B @Rn ; The post The SuperH-3, part 11: Atomic operations appeared first on The Old New Thing....
