K82: wakeup due peripherals

Hi !

 

1. I2C slave has configuration field :

"

1
WUEN  Wakeup Enable
The I2C module can wake the MCU from low power mode with no peripheral bus running when slave
address matching occurs.
0 Normal operation. No interrupt generated when address matching in low power mode.
1 Enables the wakeup function in low power mode.

"

What means low power mode here ? What exact modes are in mind ?

Do I understand right and this wakeup is transparent for MCU e.g no need any special handlers/interrupts and clean up functions ?

 

 

2. WDOG has configuration field:

 

"

STOPEN
Enables or disables WDOG in Stop mode.

"

 

What STOP mode is mentioned here ?

 

According MCU specification, all low power mode called stop modes:

 

STOP
VLPS
LLS2
LLS3
VLLS3
VLLS2
VLLS1
VLLS0

 

Regards,

Eugene
