### `m`: **MEMORY_READ**
**Read data from specified memory address**
#### `arg0` (address)
| bits | description |
| -------- | ----------------------- |
| `[31:0]` | Starting memory address |
#### `arg1` (length)
| bits | description |
| -------- | --------------------------------------- |
| `[31:0]` | Number of bytes to read from the memory |
#### `response` (data)
| offset | type | description |
| ------ | --------------- | --------------- |
| `0` | uint8_t[length] | Memory contents |
Reads bytes from the specified memory address. Please refer to the [internal memory map](./01_memory_map.md) for available memory ranges.

_This command does not send response data._
_This command does not send `RSP`/`ERR` packet response!_
This command notifies N64 that data is waiting to be acknowledged.
If N64 side doesn't acknowledge data via [`m` **USB_READ**](./02_n64_commands.md) N64 command within 1 second then data is flushed and [`G` **DATA_FLUSHED**](#asynchronous-packets) asynchronous packet is sent to the PC.
If N64 acknowledge the request, then data is written to the flashcart memory to address specified in [`m` **USB_READ**](./02_n64_commands.md) N64 command.
