Host reads transfer data in SMICDTR.
Host confirms the BUSY bit in SMICFLG.
The bit indicates slave (this LSI) is ready for receiving a new control code.
When BUSY = 1, access from host is disabled.
Host confirms the RX_DATA_RDY bit in SMICFLG.
Host writes the Read control code to SMICCSR.
Host sets the BUSY bit in SMICFLG.
Host confirms the falling edge of the BUSY bit in SMICFLG.
An interrupt is generated.
Host confirms the status code in SMICCSR.
In the case of normal completion, the status code is reflected to the next step.
In the case of abnormal completion, the status code is READY and an error
is kept.
