Programmable Interrupt Controller (PIC)
This section describes the DC and AC electrical specifications for the PIC of the MPC8569E.
2.18.1
PIC DC Electrical Characteristics
The following table provides the DC electrical characteristics for the external interrupt pins IRQ[0:6], IRQ[8:11] and IRQ_OUT
of the PIC, as well as the port interrupts of the QUICC Engine block.

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. Timers inputs and outputs are asynchronous to any visible clock. Timers outputs must be synchronized before use by any
external synchronous logic. Timers inputs are required to be valid for at least tTIWID ns to ensure proper operation.
