Pull-Up/Pull-Down Resistor Requirements
The MPC5121e/MPC5123 requires external pull-up or pull-down resistors on certain pins.
4.4.1
Pull-Down Resistor Requirements for TEST pin
The MPC5121e/MPC5123 requires a pull-down resistor on the test pin TEST.
4.4.2
Pull-Up Requirements for the PCI Control Lines
PCI control signals always require pull-up resistors on the motherboard (not the expansion board) to ensure that they contain
stable values when no agent is actively driving the bus. This includes PCI_FRAME, PCI_TRDY, PCI_IRDY, PCI_DEVSEL,
PCI_STOP, PCI_SERR, PCI_PERR, and PCI_REQ.
Refer to the PCI Local Bus specification.
4.5
JTAG
The MPC5121e/MPC5123 provides you with an IEEE 1149.1 JTAG interface to facilitate board/system testing. It also provides
a Common On-Chip Processor (COP) Interface, which shares the IEEE 1149.1 JTAG port.
The COP Interface provides access to the MPC5121e/MPC5123's embedded e300 processor and to other on-chip resources.
This interface provides a means for executing test routines and for performing software development and debug functions.
4.5.1
TRST
Boundary scan testing is enabled through the JTAG interface signals. The TRST signal is optional in the IEEE 1149.1
specification but is provided on all processors that implement the PowerPC architecture. To obtain a reliable power-on reset
performance, the TRST signal must be asserted during power-on reset.
