22 Data pulse interrupt status. Indicates when data bus pulsing occurs on DP or DM. Data bus pulsing only detected
DPIS when USBMODE[CM] equals 11 and PORTSC0[PP] is cleared. Software must write a 1 to clear this bit.
21 1 millisecond timer interrupt status. This bit is set once every millisecond. Software must write a 1 to clear this bit.
1MSS
20 B session end interrupt status. Indicates when VBUS falls below the B session end threshold. Software must write
BSEIS a 1 to clear this bit.
