22 wtc 0x0 Data Pulse Interrupt Status.
0: no pulses detected.
1: pulses detected. Write 1 to clear bit.
The pulses being detected can be on DP or DM.
Data bus pulsing is only detected when
usb.USBMODE [CM] = 11 (Host mode) and
usb.PORTSC0 [PP] = 0 (off). Non-latched status
can be read using the [DPS] bit.
1msS

21 wtc 0x0 1 millisecond Timer Interrupt Status.
0: no timer alert.
1: timer alert. Write 1 to clear bit.
The hardware sets this bit every 1 milliseconds
(based on a timer using 60 MHz ULPI).
