4.7
The SBC Stop Mode has the advantage of reducing the current consumption to a
minimum, while supplying the microcontroller with its quiescent current during its power
saving mode (“Stop”). This mode is entered via SPI command, and turns-off the
integrated bus transceivers and respective termination, but the main voltage regulator
remains active. In contrast to Cyclic Sense the HS-On state is entered once Cyclic Wake
is selected, immediately providing supply voltage at the OUTHS pin. The microcontroller
determines the duration of the HS-On state via the STS input pin (see
transitions from that HS-Off into the HS-On state are done by the selected cyclic wake
period or by a bus message. The microcontroller is notified by the WKO (Wake-Up
Output) that the HS-On state has been entered. Further notification is done in the same
way as for Cyclic Sense in Stop Mode.
