TI中文支持网问题1：参照手册设置寄存器，MCLK为16M外部输入，I2S的BCLK、WCLK及DOUT无任何信号输出。寄存器设置如下。该器件是否通电并配置主I2S寄存器0x1B的BCLK、WCLK输出就应该有时钟输出了吧？还是因为寄存器未设置正确导致？我按下面的寄存器设置了，并读取验证过，寄存器值设置是正确的。

问题二：手册上说miniDSP有18个默认处理方式，是不是说不需要Purepath studio软件来写DSP也能正常输出I2S时钟信号？
问题三：Purepath studio软件申请了好些天了，一直状态为Awaiting TI，不是说24~48小时会有答复吗？即不拒绝也不同意，等得心急啊。板都焊好了，就是没得用得软件哈。

另外，如果您这边申请Purepath有问题的话，我这边可以帮您再确认下， 所以有问题的话及时反馈。
