14.4.2 Details of Registers
• When “SYSRST=1” is set, the register settings are held and the circuits other than the registers are reset. However,
• When either “SW1SEL[2:0]=001” or “SW2SEL[2:0]=001” is set, the oscillation amplifier is set to the continuous
• When “MPSEL[1:0]=10 or 11” is set or “SW1SEL[2:0]=001” and “SW2SEL[2:0]=001” are set, the ADC is set to the
• The ADC low sampling rate operation mode performs analog to digital conversion at 6kHz, and is set during analog
• When “DIROPR=1” is set while the PLL is locked, this setting is executed after the clock source is switched to XIN.
