I believe I read somewhere (Simon's docs?) timer 4 has to do with USB. --Gbl08ma (talk) 09:19, 23 November 2014 (EST)

Simon's docs have a section on the timers for the legacy systems and the Prizm. Legacy section says 1-5 are system, 6-10 are user timers. 2 is used for syscall 0x0251 upon key presses and 4 is for USB using 0x04AE. For the Prizm, 4 is still USB using 0x1ECF. I will try to dig into these interrupt handlers and see what I can do with them.
