I guess that I should use the Data Out pins to check the status of the VoiceBox. Read out D0, when it is HIGH the buffer is half full, wait until the VoiceBox is ready (D2 HIGH) and continue.- is that the correct approach?- if so, how can I access those pins?
D2 / Buffer Half Full : Data Out 2 / Buffer Half Full Data Out 2 / Buffer Half Full output is used for flow control with a serial port by connecting to the CTS line back to the computer or controller. Or it may be used as a general-purpose output. This line is a logical output with either a High or Low logic level. Which function this output uses is determined by a configuration bit stored in the EEPROM and the factory default configurations is: "Buffer Half Full" and is Active High.
