Addressing
Figure 1.7.3 shows register bit specification.
Register bits can be specified by register directly (bit, Rn or bit, An). Use bit, Rn to specify a bit in a
data register (Rn); use bit, An to specify a bit in an address register (An).
The bits in each register are assigned bit numbers from 0 to 15, from LSB to MSB. Therefore, bit, Rn
and bit, An can be used to specify a bit number from 0 to 15.
Figure 1.7.4 shows the addressing modes used for memory bit specification. Table 1.7.1 lists the ad-
dress range in which bits can be specified in each addressing mode. Be sure to observe the address
range in Table 1.7.1 when specifying memory bits.
