3.9.8.10 FIFO Points of Attention

The partition regions must not overlap.

The partition size must be 1 or larger, and must be an integral multiple of the sample size.

The writing port and readout port must have a one-to-one relation, and the readout ports that are not
used must be disabled.

When performing power supply control of the SRAM, do not set the partition region across the 8
Kbyte and 32 KByte SRAMs.

When performing a Clear to the FIFO writing port, also make sure to perform a Clear to the
corresponding readout port.

When changing FIFO_ENABLE from Disable to Enable, make sure to perform a Clear to the FIFO
readout port.

Do not set the WATER_MARK register to "0".
3.9.9 Sequencers
The sequencers intermittently capture sensor data from the external sensors connected to the SPI, I2C or analog
input using the specified time intervals as triggers.
