MSP430FR2000: How MSP430FR2000 can work in 1M，and current 120uA

RUN“”Flashing the LED" example, The default frequency 2M，current should be 240uA according datasheet，but actual 1.1mA，although I config all IO to output ，and out=0；

And then set clock to VLO（10k，SELMS 011），current 0.9mA。

How can config to avtive mode，about 1M，and hope the current about 120uA？

WDTCTL = WDTPW | WDTHOLD; // Stop watchdog timer
PMMCTL0 = PMMPW; // Open PMM Module
PM5CTL0 &= ~LOCKLPM5; // Clear locked IO Pins
P1DIR = 0xff; // Set P1.1 to output direction
P2DIR = 0xff; // Set P1.1 to output direction
P1OUT = 0x00;
P2OUT = 0x00;

for (;;)
{
volatile unsigned int i; // volatile to prevent optimization

P1OUT ^= 0x02; // Toggle P1.1 using exclusive-OR

i = 10000; // SW Delay
do i--;
while (i != 0);
