A tak to wygląda:
Rn working register R0-R7
Direct 128 internal RAM locations, any IO port, control or status register.
For example : P1, P3, ACC
@Ri indirect internal RAM location addressed by register R0 or R1
#data 8-bit constant included in instruction
#data16 16-bit constant included in instruction
Bit 128 software flags, any IO pin, control or status bit
For example : ACC.0, P1.0, P1.1
