Motorola W24 用户手册

W24 incorporates several operating modes. Each operating mode is different in the active 
features and interfaces.

 summarizes the general characteristics of the W24 operating modes and provides 

general guidelines for operation.

VCC supply is disconnected.

The W24 is Off.
Any signals connected to the interface con-
nector must be set low or tri-state.

Valid VCC supply. All W24 voltage regula-
tors are disabled.

The W24 Interfaces and circuits are powered 
down. Only the power up/down control cir-
cuit is monitoring the IGN and ON_N sig-
nals. Any signals connected to the interface 
connector must be set low or tri-stated.

Valid VCC supply. W24 powered down by 
ON_N, while IGN set high. All W24 voltage 
regulators are active.

The W24 Interfaces and circuits are powered 
down. The CPU is running at 32kHz and 
monitoring IGN and ON_N signals. Any sig-
nals connected to the interface connector 
must be set low or tri-stated.

RESET_N signal is high.
CTS_N signal is disabled.

The W24 is in low power mode.
The application interfaces are disabled, but, 
W24 continues to monitor the Wi-Fi network.

RESET_N signal is high.
CTS_N signal is disabled.

The W24 enters deep sleep mode if it cannot 
find an AP that it can register to. It wakes up 
periodically to rescan and try to register. If 
the AP is found, it exits the deep sleep mode. 
If the AP cannot be found/registered to, it 
goes back to deep sleep mode - during that 
time it disables the RF section and does not 
monitor the Wi-Fi network.

RESET_N signal is disabled (high).
CTS_N and DSR_N signals are enabled 
(low).

The W24 is fully active, connected to the 
Wi-Fi network and ready to communicate.
This is the default power-up mode.

RF block disabled.

The W24 interfaces are fully active, but its 
RF section is disabled.

RESET_N signal is high.
TXEN_N signal is toggling.

A Wi-Fi data transmission is in progress. 
When data transmission terminates, W24 
returns to the last operating state (Idle or 
Sleep).
