Power consumption question (eZ430-RF2500)

Other Parts Discussed in Thread: MSP430F2274

 Hi,

I have a little confusion about power consumption calculation of End Device which was made in SLAA378A.

It is written there that MSp430 consumes 900nA in low-power mode 3.

However, since source clock for timer is set in ED application like that:

  BCSCTL3 |= LFXT1S_2;                      // LFXT1 = VLO
  TACCTL0 = CCIE;                           // TACCR0 interrupt enabled
  TACCR0 = 12000;                           // ~ 1 sec
  TACTL = TASSEL_1 + MC_1;                  // ACLK, upmode

 In SLAS504B it is said that if i use low power low frequency  VLO in LPM3 typical consumption is 600nA for 3V and temp 25C

So may question is if i could use that value (600nA) for my calculations of power consumption in sleeping routines of  ED ? 

Thanks,

Paul
