Figure 1.7.6 Examples of How to Specify Bit 2 of Address 0000A
(1) Bit Specification by Bit, Base
Address
Figure 1.7.5 shows the relationship between the memory map and the bit map.
Memory bits can be handled as an array of consecutive bits. Bits can be specified by a combination of
bit and base. Using bit 0 of the address that is set in base as the reference (= 0), set the desired bit
position in bit. Figure 1.7.6 shows examples of how to specify bit 2 of address 0000A
