CubeMX is limiting STM32H7A3 AHB1,2 peripheral clock in 140 MHZ.

Hi, I suppose that the STM32CubeMX V 5.5.0 has a bug for AHB1,2 Peripheral Clocks configuration for the STM32H7A/7B microcontroller.

If you try to configure the AHB1,2 clock to 280MHZ. It indicate a Clock Configuration error: "AHB1,2 Clock Frequency must be =< 140MHZ".

Is it a bug of the CubeMX or the AHB1,2 clock really must be =< 140MHZ?
