2.23 TX0 5G Group0 Target Power/ALC code (0x64h)
It defines TX0 4.9~5G target power at 54M for TSSI on case. 1step = 0.5dB.
It defines the TX0 4.9~5G ALC code 54M for TSSI off case.
Example:
TSSI on case
If system 54M target power is 13dBm, 13dBm= 13*2 = 26(dec) = 0x1A(hex)
0x64 offset should be filled with 0x1A value.
TSSI off case
If DAC ALC code value 0x0D could get 13dBm 54M power,
0x64 offset should be filled with 0x0D value.
But you might fill 0x1A to 0xF8 offset for 5G SKU usage.
2.24 TX0 5G Group0 TX Power offset low/high (0x65h~0x66h)
1step =0.5dB
Users could use TX power low/middle/high offset to do power adjustment.
0x65 = CH184~CH188 range(low channels)
0x66 = CH192~CH196 range (high channels)
Example:
If users want to make CH184 1dB higher than CH196, 0x65=0xC2 and 0x66=0x00

2.25 TX0 5G Goup1 PA TSSI Power Slop /offset (0x67h~0x68h)
Group1 = 5.18~5.24GHz range
Driver compares current TSSI value with this TSSI reference value as a base to decide if real-
time TX power compensation is required. 0xFF will be treated as invalid value.
This function is controlled by ' TSSI power compensation enable' bit (0x37 bit5).For K-free IC, TSSI
offset and slope value will be filled in MTK FT production line.
2.26 TX0 5G Group1 Target Power/ALC code (0x69h)
It defines TX0 5.18~5.24G target power at 54M for TSSI on case. 1step = 0.5dB.
It defines the TX0 5.18~5.24G ALC code 54M for TSSI off case.
Example:
TSSI on case
If system 54M target power is 13dBm, 13dBm= 13*2 = 26(dec) = 0x1A(hex)
0x69 offset should be filled with 0x1A value.
