Software configuration
On the other hand, in the slave node, the non-decoded BUS wakeup pulse is output to the CLK terminal. In
response to this, the slave node sets the NSLP pin to HIGH to transition to the Normal mode within T
wakeup_s time
.
If the slave node cannot receive the bus clock within the specified time after sending the Wakeup pulse, it will
set the NSLP pin to LOW to return to Sleep mode. Then, the Wakeup pulse can be retransmitted. A slave node
can transmit a Wakeup pulse for maximum of two times, including retransmission of the Wakeup pulse. If the
clock is not transmitted from the master node even after retransmission, the wakeup sequence can be
performed again after Sleep in physical bus error processing. (See JASO D015-3 for T
clock_start_m
time and T
wakeup_s
time).
The transition flow chart and timing chart from Sleep Mode to Normal Mode (Slave Node Trigger) are shown in
