Hello! I'm starting to learn Kinetis KL1x General Purpose MCUs, coming from MSP world. For rapid development of Cortex M0+ Core I would like to get answers to the following questions: 

    1. What is the maximum data transfer can be achieved when the data going in the external port and when reading from a port? As I understand this speed is equal to the Peripheral Module frequency - 24 MHz. Can I find anywhere Sample code which performs reading the data from the external parallel bus? I am interested in, for example, perform  reading a short sequence of data from external parallel 8-bit ADC at 24 MHz and writes it’s to the Kinetis RAM memory. Or as alternative - the realization at Kinetis KL1x synchronous FIFO controller with 24 MHz frequency and volume 2 KB? 
    2. Whether DMA may provide a data transfer rate at 24 MHz frequency?
    3. Is it possible to provide 48MHz Kinetis Core frequency when I use a 24 MHz frequency Oscillator crystal or resonator?
