The operation when no ERRCL command is entered is as follows.
<When "Transition to command standby state after power-up" is selected by the overflow of the RST counter>
*1 Misoperation detection and failure detection outputs are selected by OUTSTAT command.
*2 If transferring to the command standby state after power-up is executed by the overflow of the RST counter, each bit of
SAFE command is cleared. Also, error bits readable by RDERR command are cleared by ERRCL command.
*3 Even if transferring to the command standby state after power-up is executed by the overflow of the RST counter,
error bits readable by RDERR command and the state configured by OUTSTAT command remain.
< When "Transition to command standby state after power-up" is not selected by the overflow of the RST counter >
*1 Misoperation detection and failure detection outputs are selected by OUTSTAT command.
