hello

cyw43340  Tx power can be adjusted,I have the following questions:

Refer to otp document:

maxp2ga0=0x46,max output power is 17.5dbm,the nominal power is 17.5 – 1.0 = 16.5 dBm.

What is the actual power output if the following configuration is used:

maxp2ga0=0x46

ofdm2gpo=0x44444444(back-off power is 2dbm)

when rate is 6Mbps,The actual output power should choose which of the following?

1.max output power(17.5)-2dbm =15.5 dbm

2.the nominal power(16.5) - 2 dbm = 14.5 dbm

think you!
