引脚复用关系
引脚复用采用 iomux 进行选择，该设计中使用两级复用关系来选择一个 PAD 功能， 目的是为了第一级高速引脚具有更好的信号质量，第二级低速引脚具有更灵活的引脚功能，如下图所示 靠近 PAD 的第一级高速复用关系，具有4个可选择的功能，
当选择 hs_sel = 1/2/3 的时候, 此时选择的是 HS1/HS2/HS3 对应的接口 IP 引脚功能；
当 hs_sel = 0 时，还需要通过第二级复用关系来确定低速引脚功能，
此时根据 ls_sel 值来选择对应的低速接口 IP 引脚功能。
高速 IOMUX 复用关系
T0 芯片的高速引脚复用关系如下表，第一列 ID 表示 pad 编号；
第二列 GRP_ID 是 iomux 分组编号，表示在当前分组内的低速引脚可以映射到该组的任何一个PAD上；
第三列 HS0 则表示 hs_sel = 1 时，对应的 pad 所选择的高速功能；
第四列 HS1 则表示 hs_sel = 2 时，对应的 pad 所选择的高速功能；
第五列 HS2 则表示 hs_sel = 3 时，对应的 pad 所选择的高速功能。
