Notes:
 The above characteristics apply to CLK 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.
