MIC_L(0x7) reg * * (2) Using "Standby Bit" of STARTUP2 or STARTUP3 register * e.g. Mic left can be put to STANDBY using bit 0 of STARTUP3(0x5) * * Out of these two methods, the one using STANDBY bits is preferred * way to enable/disable individual blocks. This is because STANDBY * registers are part of system controller which allows system power * up/down in a controlled, pop-free manner. Also, as per application * note of DA7210, STANDBY register bits are only effective if a * particular IO (or ADC/DAC) is already enabled using enable/disable * register bits.
