Each level shifter output can be selected or deselected prior pattern execution start or dynamically during run-time. If a channel is deselected prior to pattern execution start, it remains in its power-up default state, which is HiZ. If a channel is deselected during run-time, it holds its current state, i.e. the output is frozen and stops toggling. When a deselected channel is selected, it resumes toggling on the next clock cycle. Channel selection bits are located in the register for GCK7-8, register for GCK12-9 and GCK4-1 and all other channels. Note that channel selection settings have no impact on succeeding channels, i.e. a master channel may be disabled without impacting a slave channel.
