No waking up from STOP mode RL78/L13

Hi,

I could see the device falled into stop mode but then it wasn't able to wake up by interval timer.

Below is the configuration:

1. The Clock:

- Low speed main mode

- fMAIN = fIH

- HSOCO  8Mhz

- fXT 32,768kHz

XT1 mode setting: Low power consumtion

STOP, HALT mode setting: stops supply

- fIL : 15kHz

- RTC/LCD = fSUB

- CPU and Prep: fCLK = fIH

2. Interval timer 0 channel 6: value 100ms. Priority : High

Generate INTTM06

3. Function: void R_CGC_Create(void)

 OSMC = _80_CGC_SUBINHALT_OFF | _00_CGC_RTC_IT_LCD_CLK_FSUB;

#define _80_CGC_SUBINHALT_OFF (0x80U) /* stops supply to peripheral functions except RTC, interval timer, PCLBUZ and LCD */
/* Selection of operation clock for highaccuracy real-time clock, 12-bit interval timer, and LCD (WUTMMCK0) */
#define _00_CGC_RTC_IT_LCD_CLK_FSUB (0x00U) /* Subsystem clock (fSUB) */

4, IRS:

static void __near r_tau0_channel6_interrupt(void)
{
     /* Start user code. Do not edit comment generated here */
     //100ms timer

     //do something


     NOP();
     //HALT();

     STOP();
     NOP();

     /* End user code. Do not edit comment generated here */

Can you please have a look into configuration

Thank you
