Notes:
1. This table applies for pins IRQ[0:7], IRQ_OUT, MCP_OUT, and CE ports Interrupts.
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% level of the signal to the 50% 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 any
external synchronous logic. IPIC inputs are required to be valid for at least tPIWID ns to ensure proper operation when working
in edge triggered mode.
