When the JTAGEN bit is unprogrammed, these four TAP pins revert to normal operation. When
programmed, the input TAP signals are internally pulled High and the JTAG is enabled for
Boundary-Scan. System Designer sets this bit by default.
For the On-Chip Debug system, in addition the RESET pin is monitored by the debugger to be
able to detect external reset sources. The debugger can also pull the RESET pin Low to reset
the whole system, assuming only open collectors on reset line are used in the application.
