• VRL outputs the operating voltage, V
• VRX outputs the operating voltage, V
26.1.2
26.1.3
This LSI includes a regulated power supply for the internal logic (VRL) and a regulated power supply for low-speed
oscillation (VRX).
The VRL outputs the operating voltage, V
The VRX outputs the operating voltage, V
For the circuit configuration of the power supplies for LCD (VL1 to VL4), see Chapter 24, “LCD Driver”.
Figure 26-1 shows the configuration of the power supply circuit.
