These bits set the value that selects the temperature curve of the V
REG
voltage to a value shown in
Table 6

.
These bits turn ON/OFF the booster circuit, reference voltage generator, control the voltage regulator circuit (V
regulator circuit) and voltage follower circuit (V/F circuit). The functions controlled by these four-power control
set command controlled by these 4 bits are listed in
Table 6
