Chapter 4Clock/ Mode/ Voltage ControlIV - 26 Voltage Control4.3 Voltage Control4.3.1 OverviewThe LSI has 3 kinds of power supply voltage; 1.1 V, 1.3 V, and 1.8 V. Depending on the operating supply voltage,operating frequency, and target value of power consumption, power supply voltage is selected and supplied toCPU, the peripheral function, RAM, and ReRAM.The relation of the output voltage, VDD18 to operating power supply voltage, operating frequency, and operatingmode is shown in the table below.Table:4.3.1 Relation of Output Voltage, VDD18 to Operating Power Supply Voltage,Frequency and Mode4.3.2 Register ListTable:4.3.2 shows a list of power supply control registers.Table:4.3.2 Power Supply Control RegistersR/W: Readable/Writable√: Enable, -: Setting is prohibited.VDD30Operating powersupply range [V]MaximumoperatingfrequencyVDD18Output voltage [V]Operating modeNORMAL SLOW HALT0/2STOP0HALT1/3STOP11.1 to 3.6 40 kHz 1.1 - √ *2 - √ *21.3 to 3.6 1 MHz 1.3 √ *1 √ *2 √ *1 √ *21.8 to 3.6 10 MHz 1.8 √ √ *2 √ √ *2*1 fSYSCLK (or fHCLK ) ≤ 1 MHz*2 16 kHz ≤ fSYSCLK ≤ 40 kHz, 32 kHz ≤ f SCLK ≤ 40 kHzSymbol Address R/W Register name PagePWCTR0 0x03F6C R/W Power supply control register 0 IV-27PWCTR1 0x03F6D R/W Power supply control register 1 IV-28
