ads1299读取连续数据时，master是否需要连续传送虚拟位元0x00至slave？

我利用MSP432P401R与ADS1299进行沟通，我利用SPI读取ADS1299连续数据，MSP432P401R为master，ADS1299为slave，在此之前我已成功利用MSP432P401R写入和读取暂存器，并且都成功，但是读取连续数据却有很大的问题。
以下为我目前遇到的几个问题整理：
1.如果要读取测试方波，并且我只需要使用一个通道，请问我的所有暂存器之值是否设定正确，通道1为内部测试讯号方波，其余通道均无讯号。
2.读取连续数据时，master是否需要连续传送虚拟位元0x00至slave。
3.读去连续数据时，每一个DRDY之间都会输出一个stat+8个通道值，因为我只使用到1个通道，我要如何让通道1的值和其余通道分开。

4.我测试过让通道1与其他通道值皆为0x61  Input shorted (for offset or noise measurements)，但结果显示我的SPI好像没有作用，无法接收到连续传输的数据，理论上应该所有数值皆为0，但结果却有数值。
以下为我目前的程式码
