Notes
1.
This may be required if DRST of the target device is an alternate-function pin and the initial value
of the OCMD0 bit changes according to the reset source. (Refer to section
3.2.8 RESET
.)
2.
This is required when the target device incorporates flash memory.
3.3.3 2.54 mm pitch 20-pin general-purpose connector
If using a 2.54 mm pitch general-purpose connector as the IE connector, mount a connector that can be
connected to the IE connection cable on the target system.
Figure 3-11 and Table 3-3 show the IE connector pin configuration and the pin functions, respectively.
