Hardware Development Interface Interconnects
The MC1322x supports two development hardware interfaces.
6.2.1
ARM JTAG Interface Connector
The MC1322x supports connection to a subset of the defined ARM JTAG connector. The JTAG hardware
interface uses a 20-pin header with a standard 0.1 inch spacing. Table 3 shows how the MC1322x pins are
connected to the associated JTAG header pinouts if the JTAG connector is provided on the application.
