b3 to b0 LVD1LVL[3:0] Voltage Detection 1 Level Select
b5, b4 LVD2LVL[1:0] Voltage Detection 2 Level Select
b7, b6 —
Note: Set the PRCR.PRC3 bit to 1 (write enabled) before rewriting this register.
When changing the LVDLVLR register, first set the LVCMPCR.LVD1E and LVCMPCR.LVD2E bits to 0 (voltage
detection n circuit disabled) (n = 1, 2).
When a setting is made so that the voltage detection level range set by the LVD1LVL[3:0] bits overlaps with the range set
by the LVD2LVL[1:0] bits, it cannot be specified which of LVD1 and LVD2 is used for voltage detection. For details on
the voltage detection level range, refer to section 32, Electrical Characteristics .
