0
Hardware Radio Control.
0: disable hardware radio control (default value).
1: enable hardware radio control.
When “hardware radio control” bit is enabled (=1), the driver will read MAC’s
GPIO
status. When GPIO pin is low, the radio is disabled. When GPIO
pin is high, the
radio is enabled.
The Radio ON/OFF is controlled by both software UI and MAC’s GPIO pin.
1
TX power temperature compensation scheme enable (TC enable)
0 : disable temperature compensation
1 : Enable temperature compensation
This bit will disable/enable temperature compensation scheme.
While this bit is enable, it means Tx power TSSI scheme is disable(0x37 bit5 = 0)
and using TC scheme.
User must fill 0x53~0x54 and 0xF2~0xF5 for TC usage.
2 External 2.4GHz band LNA.
0: Board without external LNA for 2.4GHz band must set this bit to 0.
1: Board with external LNA for 2.4GHz band must set this bit to 1 (default value).
3 External 5GHz band LNA.
0: Board without external LNA for 5GHz band must set this bit to 0.
1: Board with external LNA for 5GHz band must set this bit to 1.
4 Proprietary TEST BIT.
For debug purpose. Default value is 0.
5 2.4GHz side band for 40MHz BW.

6 5G side band for 40M BW
For debug purpose.
7
WPS Push Button Configuration control.
0: disable WPS PBC control (default value).
1: enable WPS PBC control.
The WPS PBC function is controlled through GPIO[11].
If LED mode set to “Signal strength”(64), WPS PBC will be disabled.
37h 0 40M BW in 2.4GHz band.

2.7 Frequency offset (0x3A)
Used for crystal calibration. 0x3Ais used for MTK FT test only for crystal calibration-free feature.
MTK wafer manufactory used 0x3A, bit 0~6, to store frequency offset value which is measured under
MTK FT environment. Each IC has each corresponding frequency offset .
If customers want to re-burn crystal trim value, please use 0x9F as 2nd crystal trim offset.
