4.2.1 Overview of the commands

4.2.2 WR_74_75_PARAM

With this function the parameter string of a slave according to profile S-7.4 is being

written or the data transfer with a slave according to profile S-7.5 is started.

By a slave according to profile 7.5, data have to be registered into the buffer in the

same form, as they have to be sent by AS-i.

Since the string can be longer than the command interface, it is written into the

buffer in parts at first and then it is transferred to the slave.

n is the length of the part of the string which should be written into the buffer from

index i on.
