    In data sheet STM32F103xC, STM32F103xD, STM32F103xE Table 46. Output voltage characteristics gives values of VDD–0.4 and 2.4V for TTL port and CMOS port respectively.

    Is the 2.4V a misprint? Surely the ***Output*** voltage for 8mA load is just VDD–0.4 and the TTL and CMOS designators have no meaning.

    Please clarify.
