PARAMETER MEASUREMENT INFORMATION
microcontroller serial interface timing considerations
Figure 3 shows the timing diagram for the microcontroller serial interface.
The microcontroller serial interface is designed to be compliant with 8-bit standard synchronous serial ports.
The microcontroller operates on 16-bit words; this interface consists of four pins.
UCLK:
A clock provided by the microcontroller to control access to baseband, voiceband, and auxiliary
functions registers
UDR:
An input terminal to control read and write access to baseband, voiceband, and auxiliary functions
registers
UDX:
An output terminal to transmit data from read access of baseband, voiceband, and auxiliary
functions registers
USEL:
An input terminal to enable read and write access to baseband, voiceband, and auxiliary functions
registers through the microcontroller interface
