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. |
