 ## Default Interrupt Service Handlers (ISRs)
   - V-Blank: A default V-Blank ISR is installed on startup which copies the Shadow OAM to the hardware OAM and increments the global @ref sys_time variable once per frame.
   - Serial Link I/O: If any of the GBDK serial link functions are used such as @ref send_byte() and @ref receive_byte(), the default SIO serial link handler will be installed automatically at compile-time.
-  - APA Graphics Mode: When this mode is used (via @ref drawing.h) custom VBL and LCD ISRs handlers will be installed (`drawing_vbl` and `drawing_lcd`). Changing the mode to (`mode(M_TEXT_OUT);`) will cause them to be de-installed. These handlers are used to change the tile data source at start-of-frame and mid-frame so that 384 background tiles can be used instead of the typical 256.
