Figure SCU (Sensor Control Unit)-72 Startup Control
A startup request occurs for each SEQ_ID under any of the following conditions.
A certain cycle by the timer
A certain cycle by the timer after receiving an external interrupt as the trigger
One operation using an external interrupt as the trigger
One operation using the register writing operation as the trigger, which is from the CPU
The startup intervals by the timer can be selected using the frequency division value of the Pre Divider that
determines the startup maximum frequency.
The operating frequency of each sequencer can be selected by the frequency of the 2nd power of the frequency
divided by the Pre Divider.
When the sequencer is started up by the startup request, the process is branched into each physical interface
shown below according to the setting value that is set on the SCU_RAM and hands over the external bus
transaction process.
SPI
I2C0
I2C1
When either LPADC or HPADC is selected as the physical interface, it does not branch into the external bus
transaction generation process, and the sequencer control program moves to external data capture process.
