The IOSETs are defined in the Table 7-179. NOTE For more information, see the On-Chip Debug Support / Debug Ports section of the device TRM. Table 4-27. Debug Signal Descriptions SIGNAL NAME DESCRIPTION TYPE BALL tms JTAG test port mode select. An external pullup resistor should be used on this ball.

These pins will be sampled at reset release by the test and emulation logic. Therefore, if they are used as GPIO pins, they must return to the high state whenever the device enters reset. This can be controlled by logic driven from rstoutn. After the device exits reset (indicated by rstoutn rising), these can return to GPIO mode. |
