FST Register Status
1. When FFh is written in the second bus cycle of these commands, the MCU enters read array mode.
FST5
If an error occurs, bits FST4 and FST5 in the FST register are set to 1, indicating the occurrence of an error. The
execution result can be confirmed by checking these status bits (full status check).
Table 29.6 lists the Errors and FST Register Status. Figure 29.16 shows the Full Status Check and Handling
Procedure for Individual Errors.
At the same time, the command code written in the first bus cycle is invalid.
