Started by Claro Louie August 1, 2007
hi guys,

may i ask your advice about this code below? how can you say it has an interval of 27ms? isn't it that the "32" /110010 means select NMI function;select interval timer mode;SMCLK as clock source;watchdog clock source 512 hz. default dco=1.2Mhz. this is a sample code i got from TI.com.

WDTCTL = WDT_MDLY_32;

thanks so much guys

WDT_MDLY_32 is defined in the header files included in the cross
complier/assembler/linker package. Most likely:

#define WDT_MDLY_32 (WDTPW+WDTTMSEL+WDTCNTCL)
/* 32ms interval (default) */
