Notes:
− tCYCP indicates the APB bus clock cycle time. For more information about the APB bus number to which the multi-function
serial is connected, see 8. Block Diagram in this data sheet.
− For more information about CSSU, CSHD, CSDS, and the serial chip select timing operating clock, see FM4 Family
Peripheral Manual Main Part (002-04856).
− When the external load capacitance CL = 30 pF.
