BIT SEQUENTIAL BUFFER: 16 BITS
The bit sequential buffer (BSB) is a data memory specifically provided for bit manipulation. With this buffer,
addresses and bit specifications can be sequentially updated by bit manipulation operation. Therefore, this buffer
is very useful for processing long data in bit units.
Fig. 6-9
Bit Sequential Buffer Format
Remarks 1. In pmem.@L addressing, bit specification is shifted according to the L register.
2. In pmem.@L addressing, the bit sequential buffer can be manipulated at any time regardless of MBE/
MBS specification.
