System Clock and Power-up Timing
MCLK, the master clock, must be present while ADC or/and DAC is under normal operation. Otherwise, excessive current may result
from abnormal operation of internal dynamic logic. Clock should be stopped after power-down state.
PDB pin must be set to "H" first, and then, RESETB pin must be set to "H". After RESETB pin is cleared, ADC, and DAC are still in
power-down mode. In order to activate ADC and/or DAC, write DALPD bit, DARPD bit and/or ADPD bit to "0" through A/T I/F.
Note that MCLK must be present when ADC and/or DAC is under normal operation.
MCLK should be present when all registers except for MSEL bit should be accessed. MSEL bit should be updated without MCLK
input.
MCLK can be stopped after RESETB = "L" or all of ADPD, DALPD, and DARPD are set to "1".
