我有个板子MSP430F5437的，用外部3.5V供电，程序只有
P1SEL = 0X00;
P2SEL = 0X00;
P3SEL = 0X00;
P4SEL = 0X00;
P5SEL = 0X00;
P6SEL = 0X00;
P7SEL = 0X00;
P8SEL = 0X00;
PJSEL = 0X00;
P1DIR = 0X00;
P2DIR = 0x00;
P3DIR = 0x00;
P4DIR = 0X00;
P5DIR = 0X00;
P6DIR = 0x00;
P7DIR = 0X00;
P8DIR = 0X00;
PJDIR = 0x00;
P1REN = 0XFF;
P2REN = 0XFF;
P3REN = 0XFF;
P4REN = 0XFF;
P5REN = 0XFF;
P6REN = 0XFF;
P7REN = 0XFF;
P8REN = 0XFF;
P1OUT = 0X00;
P2OUT = 0x00;
P3OUT = 0x00;
P4OUT = 0X00;
P5OUT = 0X00;
P6OUT = 0x00;
P7OUT = 0X00;
P8OUT = 0X00;
PJOUT = 0x00;
__bis_SR_register(LPM4_bits); // Enter LPM4, Enable interrupts
然后电流在400ua，
用仿真器MSP430-FET430UIF仿真时（依然是外部供电）大概是3ua,
请问这个是什么问题呢？我不接仿真器这个电流很大啊，功耗降不下去啊，急死了~~~
