  }

The eeprom block seems to be very similar across AVRs, so here is a macro to declare a "typical" one in a core.

#define AVR_EEPROM_DECLARE_8BIT

(

_vector

)

Value:

.eeprom = {                                                           \
  .size = E2END+1,                                                      \
    .r_eearl = EEARL,                           \
    .r_eedr = EEDR,                         \
    .r_eecr = EECR,                         \
    .eepm = { AVR_IO_REGBIT(EECR, EEPM0), AVR_IO_REGBIT(EECR, EEPM1) }, \
    .eempe = AVR_IO_REGBIT(EECR, EEMPE),                \
    .eepe = AVR_IO_REGBIT(EECR, EEPE),                  \
    .eere = AVR_IO_REGBIT(EECR, EERE),                  \
    .ready = {                              \
  .enable = AVR_IO_REGBIT(EECR, EERIE),                 \
    .vector = _vector,                          \
    },                                                                  \
    }

macro definition without a high address bit register, which is not implemented in some tiny AVRs.

#define AVR_EEPROM_DECLARE_NOEEPM
