(1) software reset ? it shifts to software reset with changing a register (sftrst) setting ?0? ?1?. ? i the register is returned to the initials value under the state of soft reset, and it stops accepting all address except for sftrst. ? i it?s possible to release from a state of soft reset by setting register ?1? ?0?. (2) hardware reset ? i it shifts to hard reset by changing rst pin ?h? ?l?. ? i the condition of all registers under hardware reset pin is returned to the initial value, and it stops accepting all address. ? i it?s possible to release from a state of hardware reset by setting register ?l? ?h?. (3) reset sequence ? i when hardware reset was done during software reset, software reset is canceled when hard reset is canceled. (because the initial value of soft reset is ?0? ) 2. thermal shutdown the blocks which thermal shutdown function is effective in swreg3 (step up dc/dc converter) swreg4 (inverted dc/dc converter) reg1 reg2 reg3 reg5 reg6 rega a thermal shutdown function works in about 175 o c.
