3.21.13 ADC Control Sequence
For the ADC startup and the details of the data transfer, refer to Section 3.9.13 SCU Control Sequence described
in Chapter of the SCU.
In addition, for SCU sequencer to which the LPADC and the HPADC can connect, refer to Section of
Connectable Sequencer described in Chapter of the SCU (3.9).
3.21.13.1 Setting for transferring the data of the LPADC to the GNSS
The following describes the necessary settings.
{0x200} LPADC_A0
{0x204} LPADC_A1
processing.
Procedure:
When CK_SCU_SCU is OFF, turn it ON when setting registers.
Set the registers of the LPADC
If necessary, turn CK_SCU_SCU OFF after the setting is completed
Caution: CK_SCU_U32KL is the main clock of the LPADC, therefore, it cannot be stopped when using the
LPADC.
3.21.14 Restrictions
3.21.14.1 Delay at the LPADC Startup
When starting the LPADC up, there will be maximum one sampling period of delay until the first sample is taken.
The time stamp delays according to the delay of the first sample.
3.21.14.2 Delay at the HPADC Startup
When starting the HPADC up, there will be maximum one sampling period of delay until the first sample is taken.
The time stamp delays according to the delay of the first sample.
3.21.14.3 Other Restrictions
For sequencer, MATH_PROC, and the restrictions of the time stamp, refer to Chapter of the SCU (3.9).
Select "1" when using the LPADC.
Select the four-channel AD data to send the GNSS. Then select time share
