ADCPS:
This bit sets the operation mode of the DSSP block A/D converter.
When 0, the operation mode of the DSSP block A/D converter is set to normal. (default)
When 1, the operation mode of the DSSP block A/D converter is set to power saving.
DSP SLEEP: This bit sets the operation mode of the DSP block.
When 0, the DSP block operates normally. (default)
When 1, the DSP block clock is stopped. This makes it possible to reduce power consumption.
DSSP SLEEP: This bit sets the operation mode of the DSSP block.
When 0, the DSSP block operates normally. (default)
When 1, the DSSP block clock is stopped. In addition, the A/D converter and operational
amplifier in the DSSP block are set to standby mode. This makes it possible to reduce power
consumption.
ASYM SLEEP: This bit sets the operation mode of the asymmetry correction circuit and VCO1.
When 0, the asymmetry correction circuit and VCO1 operate normally. (default)
When 1, the operational amplifier in the asymmetry correction circuit is set to standby mode. In
addition, the multiplier PLL VCO1 oscillation is stopped. This makes it possible to reduce
power consumption.
LPF SLEEP: This bit sets the operation mode of the analog low-pass filter block.
When 0, the analog low-pass filter block operates normally. (default)
When 1, the analog low-pass filter block is set to standby mode. This makes it possible to
reduce power consumption.
The DAC block clock can be stopped by setting $9 command DACPWDN (when OPSL1 = 1).
