6.10 Bit Sequential Buffer ....... 16 Bits
The bit sequential buffer (BSB) is a special data memory for bit manipulation and the bit manipulation can be
easily performed by changing the address specification and bit specification in sequence, therefore it is useful
when processing a long data bit-wise.
