VMID Reference Control Register
address_offset : 0x0 Bytes (0x0)
size : -1 bit
access : read-write
reset_value : 0x0
reset_Mask : 0x0
VMIDHPD : VMIDH Pulldown
bits : 0 - 0 (1 bit)
access : read-write
Enumeration:
#0 : 0
Release VMIDH pin for reference operation
#1 : 1
Pull VMIDH pin to ground. Default power down and reset condition
End of enumeration elements list.
VMIDHRL : Power Down VMIDH Low (4.8kΩ) Resistance Reference
bits : 1 - 1 (1 bit)
access : read-write
Enumeration:
#0 : 0
Connect the Low Resistance reference to VMIDH. Use this setting for fast power up of VMIDH. Can be turned off after 50ms to save power
#1 : 1
The Low Resistance reference is disconnected from VMIDH. Default power down and reset condition
End of enumeration elements list.
VMIDHRH : Power Down VMIDH High (360kΩ) Resistance Reference
bits : 2 - 2 (1 bit)
access : read-write
Enumeration:
#0 : 0
Connect the High Resistance reference to VMIDH. Use this setting for minimum power consumption
#1 : 1
The High Resistance reference is disconnected from VMIDH. Default power down and reset condition
End of enumeration elements list.
VMIDLPD : VMIDH Pulldown
bits : 4 - 4 (1 bit)
access : read-write
Enumeration:
#0 : 0
Release VMIDL pin for reference operation
#1 : 1
Pull VMIDL pin to ground. Default power down and reset condition
End of enumeration elements list.
VMIDLRL : Power Down VMIDL Low (4.8kΩ) Resistance Reference
bits : 5 - 5 (1 bit)
access : read-write
Enumeration:
#0 : 0
Connect the Low Resistance reference to VMIDL. Use this setting for fast power up of VMIDH. Can be turned off after 50ms to save power
#1 : 1
The Low Resistance reference is disconnected from VMIDL. Default power down and reset condition
End of enumeration elements list.
VMIDLRH : Power Down VMIDL High (360kΩ) Resistance Reference
bits : 6 - 6 (1 bit)
access : read-write
Enumeration:
#0 : 0
Connect the High Resistance reference to VMIDL. Use this setting for minimum power consumption
#1 : 1
The High Resistance reference is disconnected from VMIDL. Default power down and reset condition
End of enumeration elements list.
Microphone Bias Control Register
address_offset : 0x4 Bytes (0x0)
size : -1 bit
access : read-write
reset_value : 0x0
reset_Mask : 0x0
MICBEN : MICBIAS enable
0: Disable MIC_BIAS
1: Enable MIC_BIAS
bits : 0 - 0 (1 bit)
access : read-write
MICBVSEL : Select Microphone Bias Voltage
0: 2.4V
1: 1.7V
2: 2.0V
3: 1.3V
bits : 1 - 2 (2 bit)
access : read-write
MICBMODE : Select Reference Source For MICBIAS Generator
VMID provides superior noise performance for MICBIAS generation and should be used unless fixed voltage is absolutely necessary, then noise performance can be sacrificed and bandgap voltage used as reference.
bits : 3 - 3 (1 bit)
access : read-write
Enumeration:
#0 : 0
VMID ( VCCA/2) is reference source.
MICBIAS output ratio of VCCA
#1 : 1
VBG (bandgap voltage reference) is reference source.
MICBIAS output fixed DC voltage
End of enumeration elements list.
