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

In the pmem.@L addressing, the specified bit moves corresponding to the L register.
In the pmem.@L addressing, the BSB can be manipulated regardless of MBE/MBS specification.
