Hi,

there are examples for low power mode in this application note:

http://www.nxp.com/files/32bit/doc/app_note/AN2865.pdf

http://www.nxp.com/webapp/sps/download/license.jsp?colCode=AN2865SW

You can also use this example:

https://community.nxp.com/docs/DOC-100206

It enters STOP mode and it wakes up on edge on WKUP pin. Just do not enable the CAN sampler.

Regards,

Lukas

HI,Lukas!

Thank you very much!  

With the help of you, I can into the lower power stopped mode.  According to the following code:

ME.STOP0.B.PDO = 1; /* Pad power sequence driver disabled, */
/* but state of the output is kept */
ME.STOP0.B.MVRON = 0; /* Main Voltage regulator is off */
ME.STOP0.B.DFLAON = 1; /*Data flash is in power-down mode */
ME.STOP0.B.CFLAON = 1; /* Code flash is in power-down mode */
ME.STOP0.B.FMPLLON = 0; /* FMPLL off (default status during STOP) */
ME.STOP0.B.FIRCON = 0; /* Fast internal RC oscillator off */
ME.STOP0.B.FXOSC0ON = 0;/* Fast external crystal oscillator off */


ME.STOP0.B.SYSCLK = 0x0f; /* System clock is disabled */


ME.STOP0.B.PDO = 1; /* Pad power sequence driver disabled, */
ME.MCTL.R = 0xA0005AF0; /* Enter STOP Mode & Key */ 
ME.MCTL.R = 0xA000A50F; /* Enter STOP Mode & Inverted Key */

if   ME.STOP0.B.SYSCLK = 0x0f;         the low power current is 2.96ma  ,  but  I cannot wake up  MCU by  wakeup[4]

if   ME.STOP0.B.SYSCLK = 0x02(or 0x02);         the low power current is 16ma  ,  and  I can wake up  MCU by  wakeup[4]

Now, I need  the low power current <5ma.How can I to Configure the above code section.
