Notes:
− tCYCP indicates the APB bus clock cycle time.
About the APB bus number which multi-function serial is connected to, see 1. S6E2H Series Block Diagram in this data sheet.
− About CSSU, CSHD, CSDS, serial chip select timing operating clock, see FM4 Family PERIPHERAL MANUAL.
− When the external load capacitance CL = 30 pF.
