GPIO inputs—minimum pulse width
Notes:
1. Input specifications are measured from the 50 percent level of the signal to the 50 percent level of the rising edge of CLKIN.
2. GPIO inputs and outputs are asynchronous to any visible clock. GPIO outputs should be synchronized before use by external

Notes:
1. This table applies for pins IRQ[0:7], IRQ_OUT, and MCP_OUT.
2. IRQ_OUT and MCP_OUT are open-drain pins; thus V
