NXP Semiconductors QorIQ LX2160A - 2.13 JTAG port; 2.14 Interrupt controller

2.13 JTAG port
The JTAG port provides access to the processor using a standard 10-pin Arm Cortex
JTAG connector for debugging purposes. The following figure shows the LX2160ARDB
JTAG architecture.

2.14 Interrupt controller
Some of the LX2160A generic interrupt controller (GIC) pins are reserved for use with
RTC and different Ethernet PHYs. The remaining pins are used to merge various board-
related interrupt sources for handling by the processor, or for general GPIO use. The
interrupts are connected as shown in the figure below.
