[GPIO]设置GPIO0-3中断问题



您好,我想设置四个GPIO口的中断 分别是GPIO0—3对应Core0-3  中断事件号为90 GPINTN

1. 在初始化GPIO的时候  CSL_GpioHandle CSL_GPIO_open (Int32 instNum); 这个instNum是什么意思? 是不是每个GPIO都需要设置对应的instNum 如GPIO0 ——GPIO_open(0)、GPIO1——GPIO_open(1)?

2. CSL_GPIO_bankInterruptEnable(hGpio,bankNum), 这个banknum又是什么意思? 是不是也是要设置为 GPIO0—bank0 GPIO1—bank1 ?
