help
To reduce the amount of data throughput, adjacent samples (in each
individual channel) can be averaged and decimated on the chip by
setting this register. Set to 0 for no averaging.
0 = 1 sample (no averaging)
1 = 2 samples
2 = 4 samples
3 = 8 samples
4 = 16 samples
5 = 32 samples
6 = 32 samples

config MAX30101_FIFO_ROLLOVER_EN
bool "FIFO rolls on full"
help
Controls the behavior of the FIFO when the FIFO becomes completely
filled with data. If set, the FIFO address rolls over to zero and the
FIFO continues to fill with new data. If not set, then the FIFO is
not updated until FIFO_DATA is read or the WRITE/READ pointer
positions are changed.

Set the effective sampling rate with one sample consisting of one
pulse/conversion per active LED channel. In SpO2 mode, these means
one IR pulse/conversion and one red pulse/conversion per sample
period.
