Index Control Registers (Write to Control Address)

Either the LCNTR'/LOL' or the RCNTR'/ABG inputs can be initialized to operate as an index input. When initialized as such,

the index signal from the encoder, applied to one of these inputs performs either the Reset CNTR or the Load CNTR or the Load OL operation synchronously with the quadrature clocks. Note that only one of these inputs can be selected as the Index input at a time and hence only one type on indexing function can be performed in any given set-up. The index function must be disabled in non- quadrature count mode.
