10. DATA BUFFER (DBF)
The data buffer is used to transfer data to and from peripheral hardware and to reference tables.
10.1 DATA BUFFER STRUCTURE
10.1.1 Mapping of Data Buffer to Data Memory
Fig. 10-1 shows how the data buffer is mapped to data memory.
As shown in Fig. 10-1, the data buffer is allocated to addresses 0CH to 0FH of data memory BANK0 and
consists of 16 bits in a 4-word
Because the data buffer is mapped to data memory, it can be operated by data memory instructions.
