Low Frequency Boost Function
By controlling BST1-0 bits, the low frequency boost signal can be output from DACL, DACR and DACM. The setting
value is common in DACL, DACR and DACM.
Table 18 shows the relationship of external resistor, capacitor, fc(cut-off frequency) and output power, where load
resistance of headphone is 16
