ST-One: STM32F4xx ADC Channels

The data sheet for the STM32F4 series states that 24 external ADC input channels are available, but I can find only 23 in the pin assignments. ADC3_IN8 appears to be missing.

The F4 reference manual (RM0090) describes just 16 external channels.

Please reply with the pin assignment for ADC3_IN8 and, of course, poke your ST brethren to fix the documentation.

Cheers, Hal
