Notes:  The above characteristics apply to clock synchronous mode.

 t

CYCP indicates the APB bus clock cycle time.

About the APB bus number which Multi-function Serial is connected to, see  Block Diagram in

this data sheet.

 These characteristics only guarantee the same relocate port number.

For example, the combination of SCKx_0 and SOTx_1 is not guaranteed.

 When the external load capacitance C

L = 30 pF.
