JTAG1. Test Clock.
This is an optional JTAG interface, not enabled
by default. If enabled, it connects to Cortex-R4
only and allows the parallel debugging of the
Cortex-R4 and Cortex-M3 processors without
chaining them but using two separate JTAG
interfaces. If JTAG1 is not enabled, the debug
interface is controlled through the JTAG
dedicated interface only.
