128-bit : 1 Sample format
3.9.8.3 Partition
The SRAM for the FIFO has up to 27 partitions.
The partitions are classified as follows:
(1) Decimation Partitions
(2) Normal Sensor Partitions ... x 8 partitions
(3) Virtual Sensor Partitions ... x 10 partitions
(4) Random Access Partitions ... x 1 partition
The region of each partition is allocated by specifying an arbitrary address size from the 40 Kbytes of SRAM. The
allocation must be done under the following conditions.

The partition regions must not overlap

Each partition size must be equal to or larger than the value 1 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 set to disable.

When performing power supply control of the SRAM, the partition region must not be set across the 8
Kbytes and 32 Kbytes of the two SRAMs.
The number of each partition's writing ports/readout ports depends on the type of the partition. For clarification,
Table SCU (Sensor Control Unit)-102 shows the mnemonics for each partition name and by each writing
port/readout port.
