4.5.1.1
TRST and PORESET
The JTAG interface can control the direction of the MPC5121e/MPC5123 I/O pads via the boundary scan chain. The JTAG
module must be reset before the MPC5121e/MPC5123 comes out of power-on reset; do this by asserting TRST before
PORESET is released.
For more details refer to the Reset and JTAG Timing Specification.

4.5.2
e300 COP/BDM Interface
There are two possibilities to connect the JTAG interface: using it with a COP connector and without a COP connector.
4.5.2.1
Boards Interfacing the JTAG Port via a COP Connector
The MPC5121e/MPC5123 functional pin interface and internal logic provides access to the embedded e300 processor core
through the Freescale standard COP/BDM interface. Table 52 gives the COP/BDM interface signals. The pin order shown
reflects only the COP/BDM connector order.
