Part Number:MSP430F5507
Hi, I am working with a the TI MSP430F5507, I cannot seem to reduce the LPM4 current below 24uA.
I have removed all peripheral circuitry and I am using standard TI LPM4 function. See below
void LowPower4(void)
{
WDTCTL = WDTPW | WDTHOLD; // Stop WDT
// Setup UCS
UCSCTL4 = SELA_1; // Ensure VLO is ACLK source
// Port Configuration
P1OUT = 0x00;
P2OUT = 0x00;
P3OUT = 0x00;
P4OUT = 0x00;
P5OUT = 0x00;
P6OUT = 0x00;
PJOUT = 0x00;
P1DIR = 0xFF;
P2DIR = 0xFF;
P3DIR = 0xFF;
P4DIR = 0xFF;
P5DIR = 0xFF;
P6DIR = 0xFF;
PJDIR = 0xFF;
// Disable SVS
PMMCTL0_H = PMMPW_H; // PMM Password
SVSMHCTL &= ~(SVMHE | SVSHE); // Disable High side SVS
SVSMLCTL &= ~(SVMLE | SVSLE); // Disable Low side SVS
__bis_SR_register(LPM4_bits); // Enter LPM3
__no_operation();
}
