Description
● When operation control "EN"=1 or "EN↑"( P instruction) changes from 0→1,it will perform the read ("R/W"=1)
or write ("R/W"=0) file register operation. While reading, the content of data registers starting from Sa will be
overwritten by the content of file registers addressed by the base file register Sb and record pointer Pr; while
writing, the content of file registers addressed by the base file register Sb and record pointer Pr will be
overwritten by the content of data registers starting from Sa; L is the operation quantity or record size. The
access of file register adopts the concept of RECORD data structure to implement. For example, Sa=R0,
Sb=F0, L=10, the read/write details shown as below
Sb
Sa
R0 ~ R9
(L=10)
F0 ~ F9
(L=10)
F10 ~ F19
(L=10)
F20 ~ F29
(L=10)
F30 ~ F39
(L=10)
