Register R0 ~ R7 of the currently selected Register Bank (RB0 ~ RB3).
The address of 8-bit internal data location.
This could be an IRAM location (0x00 ~ 0x7F; 128 bytes) or a SFR (0x80 ~ 0xFF).
8-bit IRAM location (0x00 ~ 0xFF; 256 bytes) addressed indirectly through register R0 or R1.
8-bit constant included in instruction.
16-bit constant included in instruction.
16-bit destination address.
Used by LCALL & LJMP. The branch can be anywhere within the 64kbytes program memory address
space. (MiDAS1.1 Family : 4kbytes program memory)
11-bit destination address.
Used by ACALL & AJMP. The branch will be within the same 2kbytes page of program memory as the
first byte of the following instruction.
Signed (2’s complement number) 8-bit offset byte.
Used by SJMP and all conditional jumps. Range is -128 to +127 byte relative to first byte of the
following instruction.
Direct addressed bit n IRAM of SFR.
