Connectable Sequencers
3.9.9.4.1
I2C
The I2C0 and I2C1 can be connected to any sequencer from SEQ0 to SEQ9.
See Section 3.9.9.8 for the data flow.
The I2C execution command must be set beforehand in the parameter SEQ_INSTRUCTION_n (n is the
instruction number, n = 0, ..., 127) within the SCU_RAM. At each sequencer, set this instruction number in the
parameter SEQ_PROPERTY_n.INST_OFST (n is the sequencer number, n = 0, ..., 9) within the SCU_RAM.
For the I2C macro, set the fastest baud rate calculated from the frequency of the SCU clock, and when reading
out 6 Bytes from the 3 axis sensor, use the total of approximately 2,200 clock cycles for the I2C transfer. Also,
