FGPI_CTL[3:2] == 00 or 01
fgpi_buf_sync sampled during last record of buffer #1
will allow the record to finish being loaded into buffer #1
FGPI_CTL[3:2] == 10
fgpi_buf_sync sampled before last record of buffer #1
will switch to buffer #2 after storing the last sample in
buffer #1. Subsequent samples will be saved in buffer
#2. Note: the rest of buffer #1 is undefined.
