S32K I/O SPEED too slow

Question asked by jianfei zheng on Aug 9, 2018

HELLO,Recently I discovered  S32K's IO speed is not as fast as i wish。The CPU frq is 112Mhz,bus frq is 56Mhz。The IO speed is 130ns,that is 7.7MHZ。I was not use SDK but directly write the register  PDOR.As usually, IO Speed can reach the half of Bus frq.That is when bus frq is 56MHZ,io speed can reach 26Mhz.But S32K's is just 7.7MHz.Can S32K's io speed faster?
