This section describes the DC and AC electrical specifications for the external interrupt pins.
16.1
IPIC DC Electrical Characteristics
Table 51

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 t
PIWID
ns to ensure proper operation.

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
