targ

A variable that is assigned with the data byte(s)

address

The address where reading must start. This must be in the range from 0 up to the available data length - 1. So when the user signature is 32 bytes, the range is from 0-31.

bytes

The number of bytes to read. This is an optional variable. When not used the target variable data type is used to determine how many bytes must be read.
