otp_write_params |
CALIB_TXPOWBACKOFFT |
0x14C |
arg |
arg is 32-bit value specifying TX power backoff versus temperature. Bits[7:0] 2.4G at +80 degree Celsius, bits[15:8] 2.4G at -20 degree Celsius, bits[23:16] 5.0G at +80 degree Celsius, bits[31:24] 5.0G at -20 degree Celsius. Each 8-bit field is a signed value. |
otp_write_params |
CALIB_TXPOWBACKOFFV |
0x150 |
arg |
arg is 32-bit value specifying TX power backoff versus voltage. Backoff in 2.4GHz, 5GHz bands at very low voltage. Backoff in 2.4GHz, 5GHz bands at low voltage. Each 8-bit field is signed value. |
otp_write_params |
REGION_DEFAULTS |
0x154 |
arg |
Register default enable control.
arg is 32-bit value where a specific bit is set to
0 implies that the corresponding OTP field is programmed. The following list shows the bit and field mapping:bit 0 : QSPI_KEY
bit 1 : MAC0 Address
bit 2 : MAC1 Address
bit 3 : CALIB_XO
bit 4 : CALIB_PDADJMCS7
bit 5 : CALIB_PDADJMCS0
bit 6 : CALIB_MAXPOW2G4
bit 7 : CALIB_MAXPOW5G0MCS7
bit 8 : CALIB_MAXPOW5G0MCS0
bit 9 : CALIB_RXGAINOFFSET
bit 10 : CALIB_TXPOWBACKOFFT
bit 11 : CALIB_TXPOWBACKOFFV
bit 12-31 : Reserved
