I'm not an expert on the subject, but as far as I know the only
documentation on the serial interface
is found in US patent 6,609,977. If you look at the patent you will find the
following line:

"Serial interface provides a serial interface to hand controllers or other
serial devices using automatic
controller polling and bulk data mode including a light gun interface."

If you need more info about the registers, then take a look at the patent.
The entire 0xcc006400 register
range is covered there. Take a close look on the SI Communication Control
Status Register (Offset + 0x34).
You will find all interrupt related stuff there. It is possible to get an
interrupt when a "pad-poll" has completed,
but you still need to start the transfer somewhere (Writing a '1' to the
Control Status Register bit 0.) Remember also
to set bit 27 of the register to enable the TC (Transfer Complete)
interrupt.

Good luck!
