Figure 98. Two typical applications with unused I/O pin
1. I/O can be left unconnected if it is configured as output (0 or 1) by the software. This has the advantage of
During normal operation the ICCCLK pin must be pulled-up, internally or externally (external
pull-up of 10k mandatory in noisy environment). This is to avoid entering ICC mode
unexpectedly during a reset.
