Boot Update Completed Bit (SR15)
This flag indicates if the control program was properly downloaded (using the download function) to RAM.
Check Sum Consistency Bit (SR12)
This flag indicates if the check sum matches after a program is downloaded for execution (using the download
function).
ID Check Completed Bits (SR11 and SR10)
These flags indicate the result of ID checks. Some commands cannot be accepted without an ID check.
Data Reception Time Out (SR9)
This flag indicates when a time out error is generated during data reception. If this flag is set during data reception, the
received data is discarded and the microcomputer returns to the command wait state.
Full Status Check
A full-status check allows the user to review the erase and program operations. Figure 1.177 shows a full-status check
flowchart and the action to take when an error occurs.
