4.4.9Map Descriptor Example 6 – Using a Mask to Address specific module positions

There may be occasions when it is not suitable to use address and length. For example if you are attempting to address non-consecutive Optomux module positions OR when you wish to use a command that affects all module positions. The driver provides an alternate method for module position specification by allowing you to specify a mask as a parameter in the CSV file. The mask may be specified in decimal or hexadecimal format.

In this example, module positions 1 and 5 are pulsed.

Module positions are specified in hexadecimal in this example.

0x0001	= Module Position 1
0x0002	= Module Position 2
0x0003	= Module Positions 1 & 2

This function turned on the specified module positions for a specified period. Un specified positions (mask bit positions equal zero) are non affected by the command.
