PCI_FRAME, PCI_TRDY, PCI_IRDY, PCI_DEVSEL, PCI_STOP, PCI_SERR, PCI_PERR, and
PCI_REQ.
5.3.3
Pull-up/Pull-down Requirements for MEM_MDQS Pins
(SDRAM)
The MEM_MDQS[3:0] signals are not used with SDR memories and require pull-up or pull-down
resistors in SDRAM mode.
5.3.4
.
Pull-up/Pull-down Requirements for MEM_MDQS Pins (DDR
16-bit Mode)
The MEM_MDQS[1:0] signals are not used in DDR 16-bit mode and require pull-down resistors.
5.4
JTAG
The MPC5200B provides the user 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 MPC5200B's embedded Freescale (formerly Motorola) MPC603e
e300 processor. This interface provides a means for executing test routines and for performing software
development and debug functions.
5.4.1
JTAG_TRST
Boundary scan testing is enabled through the JTAG interface signals. The JTAG_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 JTAG_TRST signal must be asserted
during power-on reset.
5.4.1.1
The JTAG interface can control the direction of the MPC5200B I/O pads via the boundary scan chain. The
JTAG module must be reset before the MPC5200B comes out of power-on reset; do this by asserting
JTAG_TRST before PORRESET is released.
JTAG_TRST and PORRESET
For more details refer to the Reset and JTAG Timing Specification.
