6.9 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 large data bit-wise.
Figure 6-10. Bit Sequential Buffer Format
Remarks
1.
In pmem.@L addressing, the specified bit moves corresponding to the L register.
2.
In pmem.@L addressing, the BSB can be manipulated regardless of MBE/MSB specification.
