Address: F00F4H
The 78K0R/Kx3-L contains a circuit for operating the device with a constant voltage. At this time, in order to stabilize the
The regulator output voltage is normally 2.4 V (typ.), and in the low consumption current mode, 1.8 V (typ.).

This register sets the output voltage of the regulator.
The RMC register is set with an 8-bit memory manipulation instruction.
Reset input sets this register to 00H.
