FUNCTIONAL DESCRIPTION
1. Register Settings
The MB86434 IC chip controls all electronic volume, switching, tone generator circuits and power-down control
circuits by means of the SRD, STB and SRC data input signals.
The MB86434 uses a 9-bit serial data format consisting of a 4-bit address followed by 5 data bits. Data is picked
up at the rise of the SRC signal, and latched by the STB L-level signal. The 9-bits of serial data preceding the STB
signal are considered valid. These register settings are not reset at power-down. They can be reset when data is
initialized by an XPRST L-level signal.
