97 / 247 page  ST72344xx, ST2345xx On-chip peripherals Doc ID 12321 Rev 6 97/247 A minimum of four falling edges of the CPU clock must occur between two consecutive active edges of the external clock; thus, the external clock frequency must be less than a quarter of the CPU clock frequency. Figure 44. Counter timing diagram, internal clock divided by 2 Figure 45. Counter timing diagram, internal clock divided by 4 Figure 46. Counter timing diagram, internal clock divided by 8 Note: The device is in reset state when the internal reset signal is high. When it is low, the Device is running.
