REGISTER DESCRIPTION
6.1
Chip ID - Register 01h
Function:
This register is Read-Only. Bits 7 through 4 are the part number ID which is 1100b (0Ch) and the re-
maining bits (3 through 0) are for the chip revision.
6.2
Power Control - Address 02h
6.2.1
Freeze (Bit 7)
Function:
This function allows modifications to be made to certain control port bits without the changes taking
effect until the Freeze bit is disabled. To make multiple changes to these bits take effect simulta-
neously, set the Freeze bit, make all changes, then clear the Freeze bit. The bits affected by the
Freeze function are listed in Table 4 below.
6.2.2
Power Down MIC (Bit 3)
Function:
The microphone preamplifier block will enter a low-power state whenever this bit is set.
6.2.3
Power Down ADC (Bit 2)
Function:
The ADC pair will remain in a reset state whenever this bit is set.
6.2.4
Power Down DAC (Bit 1)
Function:
The DAC pair will remain in a reset state whenever this bit is set.
6.2.5
Power Down Device (Bit 0)
Function:
The device will enter a low-power state whenever this bit is set. The power-down bit is set by default
and must be cleared before normal operation can occur. The contents of the control registers are re-
tained when the device is in power-down.
