By default, when using my link scripts, the standard runtime is initialised by crt0 as follows:

| `0x03fffe` | ~256k | `_STACK_SIZE` |Stack (SSP). Grows towards 0. At round about 0x0000400 it would start stomping all over the memory area used by the monitor |

| `0x040000` | n/a | `_RUN_ADDRESS` | Start of user program (.text), followed by initialised data (.data) and then unititialised data (.bss). The .bss area is initialised to all zeroes before main() is called. |

You can use this option as many times as needed.

**uint8_t cpu_speed_mhz**. This uses the counter in the PI/T to figure out roughly how fast the CPU is being clocked at. Within a MHz or so.

**uint8_t cpu_type**. Figures out what CPU is installed: 0 - 68000/68008, 1 - 68010, 2 - 68020, 3 - 68030

**uint8_t running_in_rom**. When non-zero, indicates that the code is running in ROM. 0 indicates it's running in RAM.

When `main()` returns or when `exit()` is called, a non-zero exit code will be printed as follows:

No message is printed if the exit code was zero.

Control will then be passed back to the monitor
