IRQs
The COMe-cP2020 provides five IRQ inputs which can be configured for edge/level, high and low active usage. The opera-
tional mode of the IRQs is programmed via the Carrier Interrupt Mode1 and Carrier Interrupt Mode2 registers. Refer to
Chapter 3 for further information.
The following figure demonstrates the IRQ routing of the COMe-cP2020.

Miscellaneous (MISC)
These signals are normally pre-defined for an X86 architecture board and have no defined functionality on Power Architec-
ture CPUs. On the COMe-cP2020 these signals may be used as gerneral purpose output.

JTAG/Debug Interface
The COMe-cP2020 provides one JTAG/Debug connector, J4, to facilitate software debugging using an emulation probe. The
connector type is: 1x20_SAMTECH_ZF.
