Slave node trigger
After detecting an internal wakeup event, the slave node sends a Wakeup pulse to the communication bus via
the TXD pin.
In the master node, when S6BT112A receives the BUS wakeup pulse, it transmits the non-decoded wakeup
pulse to the RXD terminal. In response to this, the MCU sets NSLP pin to HIGH within T
clock_start_m
time to
transition to Normal mode, and then the master node will start transmitting the baud rate clock to the CLK pin
to transmit the clock to the communication bus.
