I2C について：
SDKとすり合わせて見ました。ほぼPT_Device.hのInitTunerと合致してますね。
ただ、//LPF Tuning Onのところから関数が終わるまで(91,11,93,13で始まるやつ)
SLEEPあるはずの場所にSLEEPが無い点がSDKと違うようです
以下前提条件
(START) = (I_DATA_H)(I_CLOCK_H)(I_DATA_L)(I_CLOCK_L)
(STOP) = (I_DATA_L)(I_CLOCK_H)(I_DATA_H)
addr_demod : S0 => 0x22, S1 => 0x26, T0 => 0x20, t1 => 0x24
addr_tuner : S0 => 0xc6, S1 => 0xc0, T0 => 0xc4, t1 => 0xc2
SDK的にはI2Cは以下の6パターン
Write : (START), addr_demod, addr, data * size (STOP)
WriteTuner : (START), addr_demod, 0xfe, addr_tuner , addr, data * size (STOP)
WriteTunerWithoutAddress: (START), addr_demod, 0xfe, addr_tuner , data * size (STOP)
Read : (START), addr_demod, addr, (START) , addr_demod | 1, [(READ) * 8, (LNOP)or(HNOP)] * size, (STOP)
ReadTuner : (START), addr_demod, 0xfe, addr , (START) , addr_demod , 0xfe, addr_tuner | 1, (START), addr_demod | 1, [(READ) * 8, (LNOP)or(HNOP)] * size, (STOP)
ReadTunerWithoutAddress : (START), addr_demod, 0xfe, addr_tuner | 1, (START) , addr_demod | 1, [(READ) * 8, (LNOP)or(HNOP)] * size, (STOP)
