"number": "6",
"name": "8-BYPASS",
"type": "input",

"name": "OSC_INH",
"type": "input",
"description": "Oscillator inhibit input; when high, disables the on-chip RC oscillator and routes the external clock signal at IN 1 to the counter; input protected by CMOS protection network."

{
"number": "15",
"name": "DECODE_OUT",
