Bit Settings Table

Some parameters are based on binary numbers, effectively meaning that a single parameter has 8 separate settings, known as Bits. Therefore when you see a reference to parameter NNNN Bit #0, this is referring to the right most Bit, and Bit #7 would be the left most. The table below shows the corresponding position of each Bit.

Bit #7 Bit #6 Bit #5 Bit #4 Bit #3 Bit #2 Bit #1 Bit #0
0 or 1 0 or 1 0 or 1 0 or 1 0 or 1 0 or 1 0 or 1 0 or 1
