Other Parts Discussed in Thread: MSP430FR5739
Hello guys,
I am trying to go into LPM3.5 on my msp430FR5739 exp board. I program the following code, and then dissconnect the programming jumpers. I am still getting 1.9mA. If I program some other code on there and then this code back on, it will sometimes go down to 1.5uA. Can anyone see any holes in my LPM code?
WDTCTL = WDTPW + WDTHOLD; // Stop WDT
P1DIR = 0;
P1OUT = 0;
P1REN = 0xFF;
P2DIR = 0;
P2OUT = 0;
P2REN = 0xFF;
P3DIR = 0;
P3OUT = 0;
P3REN = 0xFF;
P4DIR = 0;
P4OUT = 0;
P4REN = 0xFF;
PJDIR = 0;
PJOUT = 0;
PJREN = 0xFF;
UCA1CTL1 &= ~UCSWRST;
UCA0CTL1 &= ~UCSWRST;
CSCTL0_H = 0xA5;
CSCTL1 |= DCOFSEL0 + DCOFSEL1; // Set max. DCO setting
CSCTL2 = SELA_1 + SELS_3 + SELM_3; // set ACLK = VLO; MCLK = DCO
CSCTL3 = DIVA_0 + DIVS_1 + DIVM_1; // set all dividers
CSCTL4 = XT1OFF + XT2OFF;
CSCTL5 &= ~(XT1OFFG + XT2OFFG);
REFCTL0 |= REFTCOFF;
REFCTL0 &= ~REFON;
PMMCTL0_H = PMMPW_H;
PMMCTL0_L |= PMMREGOFF;
__bis_SR_register(GIE+CPUOFF+OSCOFF+SCG1+SCG0); // Enter LPM3
__no_operation();
while(1)
{}
Thanks!
