input is ignored when “Soft LOCK” is set to “1”, “LOCK SW”(DIP switch) is
ON, or a preceding calibration process is still underway.
Request
ON edge (0 → 1) in this signal triggers F159 to exchange the set of weighing
settings (m – m+19 CH in DM area) with CPU unit. Direction of data transfer
(CPU → F159, or F159 → CPU) is determined by R/W bit.
R/W
The state of this line (1/0) at the time of REQUEST trigger (0
→
1) determines
the direction of data transfer between F159 and CPU.
