Hi all,
I am testing Watchdog on mc9s08pt16, but it does not work.
Details source code as below:
#define wdog_unlock() asm(LDA #0xC5); asm(STA 0x3032); asm(LDA #0x20);asm(STA 0x3033);\
asm(LDA #0xD9); asm(STA 0x3032); asm(LDA #0x28); asm(STA 0x3033)
void wdog_enable(void )
{
DisableInterrupts;
wdog_unlock();
WDOG_CNT = 0xC520u;
WDOG_CNT = 0xD928u;
WDOG_WIN = 0x00u; /* Setup window register high */
WDOG_TOVAL = 0xF0u; /* Setup time-out value register high */
/* WDOG_CS1: EN=1,INT=0,UPDATE=1,TST=0,DBG=1,WAIT=1,STOP=1 */
WDOG_CS1 = 0xA7u; // 10100111
/* WDOG_CS2: WIN=0,FLG=0,??=0,PRES=0,??=0,??=0,CLK=2 */
WDOG_CS2 = 0x2u; /* 32 kHz internal oscillator (ICSIRCLK)*/
EnableInterrupts;
}
Main:
void main(void) {
EnableInterrupts;
wdog_enable(); // init Wdog
for (;;) {
__RESET_WATCHDOG(); /* feeds the dog */
for (;;) {
}
//__RESET_WATCHDOG(); /* feeds the dog */
} /* loop forever */
}
Looking forward to your support.
Thanks.
