Power_Sleep mode d674x (OmapL138)

Hi, i want to use Power_Sleep mode and wake-up via uart rx interrupt.
I had been taken function Power_sleepDSP(...) from Power.c and try execute

REG(RTC_KICK0R_REG) = KICK0_UNLOCK;
REG(RTC_KICK1R_REG) = KICK1_UNLOCK;

uint32_t *p = (uint32_t *)0x01810000, currMEGPD = 0;
currMEGPD = *p;
currMEGPD |= 1<<16;
*p = currMEGPD;

Power_sleepDSP(Power_SLEEP, 0, 0);

  Device reduced the power consumption, but i can't wake-up it (send data to UART from other device).

  /* *.cmd file */

SECTIONS
{
	.text:_c_int00 > 0xc3100000
    .text    : load > IRAM
    .bss     : load > IRAM
    //.far	 : load > IRAM        
    .vecs: load > IRAM
}

If i uncomment .far section, device didn't sleep. (Power_sleepDSP(...) return ti_sysbios_family_c674_Power_SOK).

About spufk5a (9.2.5) step 2:
How i can enable one interrupt and disable other ? Now i use only uart interrupt (num 69).
