V
The block diagram of the low-voltage detector is shown in Figure 22-1.
Remark EXLVI/P120/INTP0 is mounted only on 78K0/KB2-L and 78K0/KC2-L.
The low-voltage detector is controlled by the following registers.
• Low-voltage detection register (LVIM)
• Low-voltage detection level select register (LVIS)
• Port mode register 12 (PM12)
DD
This register sets low-voltage detection and the operation mode.
This register can be set by a 1-bit or 8-bit memory manipulation instruction.
The generation of a reset signal other than an LVI reset clears this register to 00H.
