This section describes the DC and AC electrical specifications for the external interrupt pins.
16.1
IPIC DC Electrical Characteristics
Table 47 provides the DC electrical characteristics for the external interrupt pins.
16.2
IPIC AC Timing Specifications

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 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. 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.
