Description
Reads a buffer from the given I2C device raw, without selecting a specific register first.
The maximum output buffer size is 0x200 for the New3DS i2c-sysmodule, and 0x20 for the Old3DS version.
This is similar to I2C:ReadDeviceRaw8, except this allows for reading a buffer instead of a single value.
