/**********************************************************************************************/FIFO Write PointerThe FIFO write pointer points to the location where the MAX30100 writes the next sample. //FIFO写指针 指向MAX30100写下一个样品的位置This pointer advances for each sample pushed on to the FIFO. //这个指针向前 将每个样品推入FIFO中It can also be changed through the I2C interface when MODE[2:0] is nonzero.//当模式[2:0]不为0时，它也能够通过I2C接口而被修改/**********************************************************************************************/FIFO Overflow CounterWhen the FIFO is full, samples are not pushed on to the FIFO, samples are lost. //当FIFO满时，样品不再被推入FIFO，样品此时丢失OVF_COUNTER counts the number of samples lost. It saturates at 0xF. //OVF_COUNTER会计数样品丢失的数量，到达0xF时 将饱和When a complete sample is popped from the FIFO (when the read pointer advances), //当一个完整的样品从FIFO被捕获时（即当读指针向前时）OVF_COUNTER is reset to zero.//OVF_COUNTER被重置为0/**********************************************************************************************/FIFO Read PointerThe FIFO read pointer points to the location from where the processor gets the next sample //FIFO读指针 指向处理器获得下一个FIFO通过I2C接口得到的样品的位置from the FIFO via the I2C interface. This advances each time a sample is popped from the FIFO. //这个指针向前 当每次从FIFO捕获一个样品时The processor can also write to this pointer after reading the samples, //如果存在一个数据交流错误 处理器 将允许从FIFO重读样品 并在读样品之后 也能够写入这个指针 which would allow rereading samples from the FIFO if there is a data communication error./**********************************************************************************************/FIFO DataThe circular FIFO depth is 16 and can hold up to 16 samples of SpO2 channel data (Red and IR). //这个供读取的FIFO深度为16，并且能够保存16个血氧饱和度通道数据样品（红光与红外）The FIFO_DATA register in the I2C register map points to the next sample to be read from the FIFO. //在I2C寄存器表中的FIFO_DATA寄存器指向下一个能够在FIFO中读取的样品FIFO_RD_PTR points to this sample. //FIFO_RD_PTR指向这个样品Reading FIFO_DATA register does not automatically increment the register addr
