(1) Regulator mode control register (RMC)
Address: F00F4H
The 78K0R/Ix3 contains a circuit for operating the device with a constant voltage. At this time, in order to stabilize
The regulator output voltage is normally 2.4 V (typ.), and in the low consumption current mode, 1.8 V (typ.).

Cautions 1. When using the setting fixed to the low consumption current mode, the RMC register can
This register sets the output voltage of the regulator.
RMC is set with an 8-bit memory manipulation instruction.
Reset input sets this register to 00H.
