Preface
Thank you very much for making use of Toshiba microcomputer LSIs. Before use this LSI, refer the section, “Points of Note and Restrictions”.
Especially, take care below cautions.
**CAUTION** How to release the HALT mode
Usually, interrupts can release all halts status. However, the interrupts = (NMI , INT0 to INT3, INTRTC, INTALM0 to INTALM4, INTKEY, INTVLD0 to INTVLD2), which can release the HALT mode may not be able to do so if they are input during the period CPU is shifting to the HALT mode (for about 5 clocks of fFPH) with IDLE1 or STOP mode (IDLE2 is not applicable to this case). (In this case, an interrupt request is kept on hold internally.
