System functions
3.1
Module power modes
Support for power save mode is available in version ODIN-W26x-01B-00.
The ODIN-W2 series module does not have an internal low power oscillator (LPO) which is required for low
power modes. An external 32.768 kHz LPO signal can be supplied externally via the LPO_CLK pin if low power
modes are required.
3.2
Module reset
The ODIN-W2 series modules can be reset (rebooted) in one of the following ways:
•
Low level on the RESET_N pin, which is normally set high by an internal pull-up. This causes «hardware”
reset of the module. The RESET_N line should be driven by an open drain, open collector or contact
switch.
•
Using a reset AT command (see the
ODIN-W2 AT Commands Manual [1]
). This causes «software” reset
of the module.
3.3
System IO
The module has the following six different configurable IOs that can be used to indicate different system states
or to be used as inputs, thus setting the module in different states:
•
SWITCH_0
•
RED
•
GREEN/SWITCH_1
•
BLUE
•
UART_DTR
•
UART_DSR
See the Pin definition section for more information on the separate IOs. For more information on the use and
configuration of the System IOs, see the
ODIN-W2 AT Commands Manual [1]
