Parameter Write Enable:
Setting this bit to 1 and the WLAN_CR register EEM1=EEM0=1 enables the
WLAN_ANAPARM register to be written via software.

Fast Back to Back Enable:
1: Enable
0: Disable
Description
Reserved
Key Mode: The combination of these two bits indicate what kind of security
scheme is being used.
01: WEP40, 01: WEP104
Reserved
TX Security ON:
Set this bit to 1 to turn on the option security scheme of the Tx path. This bit is
written by software and is invalid when WEP40 (bit 7, WLAN_CONFIG0), and
WEP104 (bit 6, WLAN_CONFIG0) are set to 0.
RX Security ON:
Set this bit to 1 to turn on the option security scheme of the Rx path. This bit is
written by software and is invalid when WEP40 (bit 7, WLAN_CONFIG0), and
WEP104 (bit 6, WLAN_CONFIG0) are set to 0.
Description
VCO Power Down:
1: VCO Power Down mode. Setting this bit will enable VCOPDN pin and turn
off the external RF front end power (includ ing VCO) and most of the internal
power of the RTL8181.
0: Normal working state. This is the power-on default value.
Power Off:
1: Power Off mode. Turn off the external RF front end power (excluding VCO)
and most of the internal power of the RTL818 1.
0: Normal working state. This is the power-on default value.
Power Management:
1: Power Management mode. Set Tx packet’s power management bit to 1 include
control type frame.
0: Normal working state. This is the power-on default value.
Reserved
Radio Front End Programming Method: The combination of these two bits
indicate what kind of the RF module is being used with the RTL8181.
