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 = 50pF.
