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.
Timings are measured at the pin.
2. GPIO inputs and outputs are asynchronous to any visible clock. GPIO outputs should be synchronized before use by external
synchronous logic. GPIO inputs must be valid for at least tPIWID ns to ensure proper operation.
16 IPIC
This section describes the DC and AC electrical specifications for the external interrupt pins.

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 VOH is not relevant for those pins.

Notes:
1. Input specifications are measured at the 50 percent level of the IPIC input signals. Timings are measured at the pin.
2. IPIC inputs and outputs are asynchronous to any visible clock. IPIC outputs should be synchronized before use by external
synchronous logic. IPIC inputs must be valid for at least tPICWID ns to ensure proper operation in edge triggered mode.
