• Manufacturer Part Number: ppc8572elpxavnd
• Description: Mpc8572e Powerquicc Iii Integrated Communications Processors
• Manufacturer: Freescale Semiconductor, Inc

At recommended operating conditions with OV
11 Programmable Interrupt Controller
In IRQ edge trigger mode, when an external interrupt signal is asserted (according to the programmed
polarity), it must remain asserted for at least 3 system clocks (SYSCLK periods).
12 JTAG
This section describes the AC electrical specifications for the IEEE 1149.1 (JTAG) interface of the
MPC8572E.
