Memory access functions.
This module provides functions for reading and writing to simulated memory. The Memory class is a subclass of AvrClass.

Memory* mem_new | ( | int | gpwr_end, |
int | io_reg_end, | ||
int | sram_end, | ||
int | xram_end | ||
) |
Allocates memory for a new memory object.

) |
Attach a device to the device list.
Devices that are accessed more often should be attached last so that they will be at the front of the list.
A default virtual device can be overridden by attaching a new device ahead of it in the list.

mem | A pointer to the memory object. |
addr | The address to fetch from. |
val | A pointer where the value of the register is to be copied. |
buf | A pointer to where the name of the register should be copied. |
