5.3- Power-up, Reset and Serial Setup:
When the SmartWAV 2 device comes out of a power up or reset, a
50ms delay before sending any command must be met, this time let
the processor to configure its internal state machines, do not attempt
to communicate with the module before this period. Any command
could be sent after this time.
The processor is configured to work at a standard default baud rate
of 57600bps. This baud rate speed can be changed from 9600bps up
to 256000bps with the corresponding baud rate change command.

selection pin, the combination of M0,
M1 and M2, determines the working
mode of the processor. Internally
pulled-down to ground via a 40K
resistor.
2
M1
INPUT
Digital input power ON/reset mode
selection pin, the combination of M0,
M1 and M2, determines the working
mode of the processor. Internally
pulled-down to ground via a 40K
resistor.
3
M2
INPUT
Digital input power ON/reset mode
selection pin, the combination of M0,
M1 and M2, determines the working
mode of the processor. Internally
pulled-down to ground via a 40K
resistor.
4
RESET
INPUT
Digital input reset pin, an active low
pulse greater than 100ns will reset the
processor. Internally pulled-up to 3.3V
via a 40K resistor. 5V tolerant input.
