Macro Definition Documentation

#define AVR_IOCTL_WATCHDOG_RESET   AVR_IOCTL_DEF('w','d','t','r')

#define AVR_WATCHDOG_DECLARE	(		_WDSR,
			_vec
	)

Value:

.watchdog = {                               \
    .wdrf = AVR_IO_REGBIT(MCUSR, WDRF),                 \
    .wdce = AVR_IO_REGBIT(_WDSR, WDCE),                 \
    .wde = AVR_IO_REGBIT(_WDSR, WDE),                   \
    .wdp = { AVR_IO_REGBIT(_WDSR, WDP0),AVR_IO_REGBIT(_WDSR, WDP1), \
	     AVR_IO_REGBIT(_WDSR, WDP2),AVR_IO_REGBIT(_WDSR, WDP3) },  \
    .watchdog = {                           \
      .enable = AVR_IO_REGBIT(_WDSR, WDIE),             \
      .raised = AVR_IO_REGBIT(_WDSR, WDIF),             \
      .vector = _vec,                           \
    },                                  \
  }

This helps declare a watchdog block into a core.

No guarantee it will work with all, but it works with the one we have right now

#define AVR_WATCHDOG_DECLARE_128	(		_WDSR,
			_vec
	)

Value:

.watchdog = {                               \
  .wdrf = AVR_IO_REGBIT(MCUCSR, WDRF),                  \
    .wdce = AVR_IO_REGBIT(_WDSR, WDCE),                 \
    .wde = AVR_IO_REGBIT(_WDSR, WDE),                   \
    .wdp = { AVR_IO_REGBIT(_WDSR, WDP0),AVR_IO_REGBIT(_WDSR, WDP1), \
    AVR_IO_REGBIT(_WDSR, WDP2) },                   \
    .watchdog = {                           \
  .enable = AVR_IO_REGBIT(_WDSR, 6),                    \
    .raised = AVR_IO_REGBIT(_WDSR, 7),                  \
    .vector = _vec,                         \
    },                                  \
    }
