两片28069芯片关于SPI主从引脚配置问题

社区大神,关于SPI主从模式引脚配置都是这样吗?还是主从模式的引脚配置不一样

 GpioCtrlRegs.GPAPUD.bit.GPIO16 = 0;   // Enable pull-up on GPIO16 (SPISIMOA)    

 GpioCtrlRegs.GPAPUD.bit.GPIO17 = 0;   // Enable pull-up on GPIO17 (SPISOMIA)    

GpioCtrlRegs.GPAPUD.bit.GPIO18 = 0;   // Enable pull-up on GPIO18 (SPICLKA)    

GpioCtrlRegs.GPAPUD.bit.GPIO19 = 0;   // Enable pull-up on GPIO19 (SPISTEA)    

 

GpioCtrlRegs.GPAQSEL2.bit.GPIO16 = 3; // Asynch input GPIO16 (SPISIMOA)    

GpioCtrlRegs.GPAQSEL2.bit.GPIO17 = 3; // Asynch input GPIO17 (SPISOMIA)    

 GpioCtrlRegs.GPAQSEL2.bit.GPIO18 = 3; // Asynch input GPIO18 (SPICLKA)    

 GpioCtrlRegs.GPAQSEL2.bit.GPIO19 = 3; // Asynch input GPIO19 (SPISTEA)

 

    GpioCtrlRegs.GPAMUX2.bit.GPIO16 = 1; // Configure GPIO16 as SPISIMOA  

   GpioCtrlRegs.GPAMUX2.bit.GPIO17 = 1; // Configure GPIO17 as SPISOMIA    

 GpioCtrlRegs.GPAMUX2.bit.GPIO18 = 1; // Configure GPIO18 as SPICLKA    

GpioCtrlRegs.GPAMUX2.bit.GPIO19 = 1; // Configure GPIO19 as SPISTEA

那如果SPI主从一对多呢?怎么配置引脚啊?
