Terminal In/Out Function 1 NC - Not used 2 B.S.2. The following table shows the pin function of IC101. POWER AMPLIFIER (IC101: TA8248K) The power amplifier is a two-channel amplifier with standby switch. 6 - FILTER BLOCK Since the sound signals from the CPU is stepped waveforms, the filter block is added to smooth the waveforms. In accordance with command from the CPU, the LSI is capable of displaying up to 16 character
