Following are the options available to

access different bit positions:

1. Register direct.

2. Absolute addressing.

3. Address register indirect.

4. Address register relative.

5. SB relative.

6. FB relative.

7. FLG direct.

When using register direct mode, the specified bit of the

registers A0, A1, R0-R3 becomes the object of the processing. In the

next addressing mode, absolute addressing, the target bit is specified with

reference to the bit zero position of the location indicated by a base register. For

this addressing mode, bits at the range 00000H to 01FFFH can become the object

of the operations.

The address registers, A0 and A1 play a role in indicating the target bit location

when using address register indirect mode. Contents of these address registers

indicate the number of bits away from the bit zero at the address 00000H to point
