4.1.1.1 Input Selection (CLKIN_SEL Register)

The CLKIN_SEL register allows selection to determine which inputs are buffered to which outputs. The drop-down menu options are:

  • 0x0: CLKIN0 → BANK0: Input given to CLKIN0 is buffered to all outputs
  • 0x1: CLKIN0 → BANK0 & CLKIN1 → BANK1: Input given to CLKIN0 is buffered to outputs on BANK0 and inputs given to CLKIN1 is buffered to outputs on BANK1.
  • 0x3: CLKIN1 → BANK1: Input given to CLKIN1 is buffered to all outputs.
