General characteristics (continued)
Figure 52. Two typical applications with unused I/O pin
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
I/O can be left unconnected if it is configured as output (0 or 1) by the software. This has the
advantage of greater EMC robustness and lower cost.
