Activate, Idle and
Sleep Modes
Sleep, idle and activate commands are located in the Command Register (0x03). These
three commands are general commands for the TSS461C.
Idle and Activate
Commands
After reset, the TSS461C starts in idle mode. In this mode, the oscillator operates
(CKOUT pin active) but the circuit cannot transmit or receive anything on the VAN bus.
The TxD output (pin 18) is in three-state mode, a pull-up resistor must be provided
externally or by the line driver to avoid floating state on the VAN bus.
To activate the TSS461C, the user must set the activate bit (ACTI) and reset the idle bit
(IDLE).
Figure 29.
Idle and Activate Timings
In both cases, the idle state can be verified by reading the Line Status register (0x04).
Sleep Command
If the user sets the sleep bit (SLEEP), the TSS461C enters in sleep mode, whatever are
the values of activate and idle bits. All non-user registers are setup to reduce the power
consumption and the internal oscillator is immediately stopped. However, all user regis-
ters (accessible by μP bus) are always available by the user
To exit from this mode, the user must set either the idle bit or the activate bit.
In a typical application (Figure 1) using the CKOUT feature (pin 12), if the TSS461C is
put in sleep mode, the clock provided to the microcontroller is stopped. So, the system
does not run and the only way to awake this application is an external reset.
