Transition from Sleep mode to Normal mode

4.1.3.1

Master node trigger

When the master node detects an internal factor event such as sensor detection in Sleep mode, it sets the NSLP
pin of S6BT112A to HIGH to transition back to Normal mode. In addition, the master node will transmit the
baud rate clock to the transceiver CLK pin to transmit the clock to the communication bus.
In the slave node, when S6BT112A receives the BUS clock, it outputs the non-decoded clock signal from the CLK
terminal. With that as a trigger, the MCU sets the NSLP pin of S6BT112A to HIGH within T
transition to Standby mode. Upon receiving the clock from the bus, and the slave node will transition to Normal
mode (see JASO D015-3 for T
Application Note
time) from standby mode.
