6. 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 1101b (0Dh), and the remaining
bits (3 through 0) indicate the device revision as shown in Table 5 below.
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 simultaneously, set the
Freeze bit, make all changes, then clear the Freeze bit. The bits affected by the Freeze function are listed
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.
