This section describes the DC and AC electrical specifications for the external interrupt pins of the
MPC8349E.
15.1
IPIC DC Electrical Characteristics
Table 44 provides the DC electrical characteristics for the external interrupt pins of the MPC8349E.
15.2

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% 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 tPICWID ns to ensure proper operation
when working in edge triggered mode.
