(Note 1) The Index command is executed after setting R numbers to Rn to Rn+3 and writing data in
the file registers (Rs) each corresponding to the R numbers. However, data setting to the
parameter (Rp) is done once before execution of the Index command; this is to prevent the
error code from being cleared.
(Note 2) The error code stored in bit F of the parameter (Rp) is not cleared even if the Index
command activating signal (ACT) goes off.
