One Channel Speech Controller

5.7 Push-Pull Output

An 8-level volume control Push-Pull Direct Drive circuit is built-in SNC12040. The

maximum resolution of Push-Pull is 7 bits. Two huge output stage circuits are

designed in SNC12040. With this advanced circuit, the chip is capable of driving

speaker directly without external transistors.

5.8 Watch Dog Timer

SNC12040 built an internal WDT (Watch Dog Timer). This Watchdog timer would

issue resets signal to this chip if it is not cleared before reaching terminal count (1sec).

The watchdog timer is enabled at reset and cannot be disabled.

5.9 IR Function

P33 can be modulated with 38.5KHz square wave before sent out to P33 pin.

The IR signal can be achieved by this modulated signal.
