AN-000324 – ICM-42607x/42670x FIFO Usage

Overview

In ICM-42607x/42670x the storage memory consists of the system memory, which is shared with other functions. System memory is a slave peripheral connected to the internal bus (SOI bus) used by APEX and FIFO bus masters. Any FIFO read operation in Accel-Low-Power-only mode or Sleep mode cannot rely on memory access because FIFO memory read/write operations take place only when the system clock is active.
