The micro-controller does not implement timer2 down-counting mode or the down-count
enable bit(T2MOD, bit0). The timer2 overflow output is active for one clock cycle. In the
DS80C320, the timer2 overflow output is a square wave with a 50% duty cycle.

3.3. USB Pipes
SPCA514A supports the following four USB pipes.
Default pipe (EP0): process the standard and vendor commands.
INTERRUPT-IN pipe (EP1): transmit device events (interface 0)
BULK-IN pipe (EP2): upload data to the PC (interface 0)
BULK-OUT pipe (EP3): download data and ROM code (interface 0)
All standard commands, except the Get Descriptor command, are processed by
hardware. For Get Descriptor command and vendor commands, the USB controller latches
