*1: The external bus clock (MCLKOUT) is a divided clock of HCLK.
For more information about setting of clock divider, see CHAPTER 14: External Bus Interface in FM4 Family
Peripheral Manual Main Part (002-04856).
*2: Generate MCLKOUT at setting more than four divisions when the AHB bus clock exceeds 100 MHz.
