Hi,

I use KSDK1.3.0 component library version set MK22FN512 clock system in KDS, found the external bus clock maximum is 30MHz, but if the kinetis component library version external bus clock maximum is 60MHz. this is what reason? I would like to work in KSDK1.3.0 component library version so that the external bus clock works at 60MHz, can you?

Thank you

Andy

Hello Andy,

Please check the Reference Manual of MK22FN512VLL12,

the Maximum FlexBus clock(External bus clock) is 30MHZ.

Hope it helps

Have a great day,
Alice Yang
