1 Introduction
The CC1100, CC1101, CC1100E, and
CC2500 all have Wake on Radio (WOR)
functionality, which enables the radio to
periodically wake up from SLEEP mode
and listen for incoming packets without
MCU interaction. After a programmable
time in RX, the chip goes back to the
SLEEP unless a packet has been
received. The purpose of this application
note is to explain the theory of operation
and the different registers involved when
using Wake on Radio, as well as
highlighting important aspects when using
WOR mode. Figure 1 shows the
relationship between the WOR events and
the different radio states.
