Two additional parameters are described below for completeness.
• WH determines how long the XBee RF module will hold a message for the
• SO is a conditional flag and determines whether the XBee RF module will wake the
There are several important ramifications and interactions with the operation of other
function calls to consider when using the sleep mode.
• When the Rabbit 4000 microprocessor wakes up from sleep, both the RCM4510W and
