Note:
It is possible to power the IOVDD pin at 1.8 V from the DC-DC output (1V8). However, the 1V8 output is off by default, and
IOVDD must be powered when programming the device. Any system that powers IOVDD directly from 1V8 must power IOVDD exter-
nally during initial programming.
Two common debug interface options are shown in
Figure 5.3 Common Debug Connections on page 69
. Refer to AN958 for more
information and additional options.
