-include usage-
- #include "wd.h" //if in same directory as project
- #include <avr/wd.h> //if wd.h is in avr directory
-
-set watchdog modes and prescale
-
-usage-
- WD_SET(mode,[timeout]); //prescale always set
-
-modes-
- WD_OFF disabled
- WD_RST normal reset mode
- WD_IRQ interrupt only mode (if supported)
- WD_RST_IRQ interrupt+reset mode (if supported)
-
-timeout-
- WDTO_15MS default if no timeout provided
- WDTO_30MS
- WDTO_60MS
- WDTO_120MS
- WDTO_250MS
- WDTO_500MS
- WDTO_1S
- WDTO_2S
- WDTO_4S (if supported)
- WDTO_8S (if supported)
-
-examples-
- WD_SET(WD_RST,WDTO_1S); //reset mode, 1s timeout
- WD_SET(WD_OFF); //watchdog disabled (if not fused on)
- WD_SET(WD_RST); //reset mode, 15ms (default timeout)
- WD_SET(WD_IRQ,WDTO_120MS); //interrupt only mode, 120ms timeout
- WD_SET(WD_RST_IRQ,WDTO_2S); //interrupt+reset mode, 2S timeout
-
-
-for enhanced watchdogs, if the watchdog is not being used WDRF should be
-cleared on every power up or reset, along with disabling the watchdog-
- WD_DISABLE(); //clear WDRF, then turn off watchdog
