4.2 Stop Mode  
In Stop Mode the contents of the TRC104 configuration registers are maintained, and the digital voltage regulator  
and parts of the digital circuitry are enabled. The remaining digital and analog circuitry is disabled to minimize  
current consumption, which is typically 1.4 µA. No serial transaction can occur in Stop Mode. The typical turn-on  
time from Stop Mode is 1.5 ms. Any operation to the TRC104 must wait until the turn on period is complete.  
Figure 10 demonstrates the states of the mode control pins and the timing related to Stop Mode.

4.3 Standby Mode  
Stand-by Mode is a low current mode that provides a very low transition time to configuration, transmit or receive  
modes. In Standby Mode circuit blocks that are not being utilized are shutdown to minimize current usage. When  
the TRC104 is set to Transmit, Receive or Configuration Mode, there is no start-up delay and the next action may  
occur immediately. The power consumption of Standby Mode is dictated mainly by the crystal frequency used.  
4.4 Configuration Mode  
Configuration Mode allows access to the TRC104s configuration registers. Serial data is applied to the SDAT pin  
and serial clock is applied to the SCLK pin. See Section 5 for additional details.  
4.5 Transmit/Receive Mode  
This mode is enabled to load the transmit FIFO or receive data. The mode function, transmit or receive, is set  
before enabling this mode. The mode function is selected by the C_Mode bit in configuration register 0x00. See  
Section 5 for descriptions and timing of the various data transfer modes.
