请问PIC32 mm的软替换（）是否正确替换？

这就是我在MX和MZ上都用到的，并且可以工作：编辑：如果内存提供服务，在执行上面的代码之前，您需要解锁序列。



      以下为原文

    This is what I use on both MX and MZ and works:

    RSWRSTSET = _RSWRST_SWRST_MASK;
    RSWRST;
    while(1);

 
Edit: if memory serves you need the unlock sequence before executing the code above.

谢谢你的回复。我实际上在MX手册中找到了类似的序列，只是不确定如果在PIC32 MMHTTP://WW1.MICCHIP.CON/DeLoSs/En/DeVICECD/61118B.PDF页11中工作的方式是相同的，除了解锁之外，它还需要同时或4个NOP。

    Thank you for reply.
 
I actually found the similar sequence int the MX manual, just not sure if this works the same way on PIC32MM
http://ww1.microchip.com/downloads/en/DeviceDoc/61118B.pdf  page 11
In addition to the Unlock, it requires while or 4 NOPs at the end as well

/* perform a system unlock sequence */
SYSTEMUnlock();
/* set SWRST bit to arm reset */
RSWRSTSET = 1;
/* read RSWRST register to trigger reset */
volatile int* p = &RSWRST
*p;
/* prevent any unwanted code execution until reset occurs*/
while(1);

实际上我尝试了_u pic32_._reset()，我在最初的文章中提到过，它也可以工作。我找到了另一本手册，它涉及整个P32家族，并且如果具有类似的序列：http://ww1.micro..com/...eviceDoc/60001118H.pdf。



      以下为原文

    I actually tried __pic32_software_reset() that I mentioned in the initial post and it works as well.
 
I found another manual that refer to the whole P32 family and if has a similar sequence:

/* The following code illustrates a software Reset */
// assume interrupts are disabled
// assume the DMA controller is suspended
// assume the device is locked
/* perform a system unlock sequence */
// starting critical sequence
SYSKEY = 0x00000000; //write invalid key to force lock
SYSKEY = 0xAA996655; //write key1 to SYSKEY
SYSKEY = 0x556699AA; //write key2 to SYSKEY
 
 
/* set SWRST bit to arm reset */
RSWRSTSET = 1;
 
/* read RSWRST register to trigger reset */
unsigned int dummy; dummy = RSWRST;
/* prevent any unwanted code execution until reset occurs*/
while(1);
