The operation when no ERRCL command is entered is as follows.

< When "Transition to the 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 the state after PUP command input" is not selected by the overflow of the RST counter >

*1 Misoperation detection and failure detection outputs are selected by OUTSTAT command.
