5.1.6
In order to facilitate system testing, the MPC8572E provides a JTAG test access port (TAP) that complies
with the IEEE 1149.1 boundary-scan specification. The common on-chip processor (COP) is part of the
MPC8572E’s JTAG machine and is implemented as an additional set of instructions/logic. The 16-pin
JTAG port allows third party debug tools to be connected to the MPC8572E to allow extensive system
debug.
