3.9.15 Restrictions
3.9.15.1 Parameter Initialization and Change Timing

Overall SCU_RAM

The SCU_RAM must be initialized before releasing the reset of the internal sequencer.

In general, the parameters within the SCU_RAM can only be changed when the functions of the related
internal sequencers are stopped.
For the restrictions on each parameter, refer to the descriptions in Section 3.9.12.11.

ADC_PROPERTY.*_ENABLE
Set ADC_PROPERTY.*_ENABLE to enable before enabling the *_D2.*_EN within the
SCU_ADCIF_REG.

The SCU_RAM cannot be accessed during SLEEP.
3.9.15.2 Decimation Partition Input Data
The data input to the decimation partition (all paths to the Write FIFOs) must be Calculation Operable Type.
This restriction is the same during FORTH_THROUGH mode and when the decimation ratio is 1.
3.9.15.3 Preprocessing of MATH_PROC
During preprocessing of the MATH_PROC, when the flag to convert from Unsigned to Signed is ON, the input
performs conversion to 2's complement format as offset binary (the offset is equal to (input value binary
maximum value + 1)/2).
The following table shows conversion examples to 2's complement format when 4 bits.
Nn_R1_C_UNDER_RUN
