Function
(1) Reads data from transfer destination network number specified by n, using routing
information set by the routing parameters, and stores it into the area starting from
(2) If no data for the transfer destination network number specified by n is set at the routing
parameters, stores 0 into the area starting from
(3) The contents of the data stored in the area starting from
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
