TIMx, is used as a general term in which x stands for 1, 2, 3, 4, 6, 7, 15, 16, 17. Table 109. IWDG min/max timeout period at 32 kHz (LSI) Note: For the values in this table, the exact timings still depend on the phasing of the APB interface clock versus the LSI clock, so that there is always a full RC period of uncertainty.
