Bit[6] : 0 : decrease power , 1 :increase power
2.19 Tx1 2.4G PA TSSI Power Slop /offset (0x5Ch~0x5Dh)
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.
2.20 TX1 2.4G Target Power/ALC code (0x5Eh)
It defines TX1 2.4G target power at 54M for TSSI on case. 1step = 0.5dB.
It defines TX1 2.4G 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)
0x5E offset should be filled with 0x1A value.
TSSI off case
If DAC ALC code value 0x0D could get 13dBm 54M power,
0x5E offset should be filled with 0x0D value.
You might fill 0x1A value to 0xF7 offset for 2G SKU usage.
2.21 TX1 2.4G TX Power offset low/middle/high (0x5Fh~0x61h)
1step =0.5dB
Users could use TX power low/middle/high offset to do power adjustment.
0x5F = CH1~CH5 range(low channels)
0x60 = CH6~CH10 range (middle channels)
0x61 = CH11~CH14 range (high channels)
Example:
If users want to make CH1 1dB higher than CH11, 0x5F=0xC2 and 0x61=0x00

2.22 TX0 5G Goup0 PA TSSI Power Slop /offset (0x62h~0x63h)
Group0 = 4.9~5GHz 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
