\version 5.10

<br>Changes to version V5.01:<br>
V5.10 ESC1: Update address register offset for 32Bit ESC access<br>
V5.10 ESC2: Check if defined SM settings do not exceed the available DPRAM range (in error case AL Status 0x14 is returned)<br>
V5.10 ESC3: Handle DC cControl register values in case of 32Bit ESC access (a Sync activation mask need to defined/used)<br>
