Interface Connector For Jtag/Once Serial Port - Motorola Freescale Semiconductor M-Core MMC2001 Reference Manual

The external command controller acts as the medium between the MMC2001 target
system and a host computer. The external command controller circuit acts as a serial
debug port driver and host computer command interpreter. The controller issues
commands based on the host computer inputs from a user interface program which
communicates with the user.

16.15 Interface Connector For JTAG/OnCE Serial Port

Figure 16-12 shows the recommended connector pinout and interface requirements
for debug controllers that access the JTAG/OnCE port. The connector has two rows
of seven pins with 0.1 inch center-to-center spacing between pins in each row and
each column.
TARGET VDD
Wired Or with target reset
circuit. This signal must be
able to assert/monitor system
reset.
Note: GPIO/SI and GPIO/SO are not required for OnCE operation at this time.
These pins can be used for high speed downloads with a recommended interface.
