2.16 TX0 2.4G PA TSSI Slop /offset (0x56h~0x57h)
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.
2.17 TX0 2.4G Target Power/ALC code (0x58h)
It defines TX0 2.4G target power at 54M for TSSI on case. 1step = 0.5dB.
It defines TX0 2.4G ALC code 54M for TSSI off case.
Example:
TSSI on case
If system 54M target power is 13dBm setting, 13dBm= 13*2 = 26(dec) = 0x1A (hex).
0x58 offset should be filled with 0x1A.
TSSI off case
If DAC ALC code value 0x0D has 13dBm 54M power performance, 0x58 offset should be filled with
0x0D.
You might fill 0x1A value to 0xF7 offset for 2G SKU usage.
2.18 TX0 2.4G TX Power offset low/middle/high (0x59h~0x5Bh)
1step =0.5dB
Users could use TX power low/middle/high offset for power adjustment.
0x59 = CH1~CH5 range (low channels)
0x5A = CH6~CH10 range (middle channels)
0x5B = CH11~CH14 range (high channels)
Example:
If users want CH1 1dB higher than CH11, 0x59=0xC2 and 0x5B=0x00
