Data Buffer (DBF)
The data buffer on the data memory is used for data transfer to and from peripheral hardware and for storage of
data during table reference.
(1) Functions of the Data Buffer
The data buffer has two major functions: a function to transfer to and from hardware and a function to read
constant data from the program memory (for table reference). Figure 4-8 shows the relationship between the
data buffer and peripheral hardware.
