• Manufacturer Part Number: USB97C201-MN
• Description: USB 2.0 ATA/ ATAPI Controller
• Manufacturer: SMSC [SMSC Corporation]

Note: These bits are masked by the SIE_MSK register and OR’d to drive the INT3 interrupt line into the 8051 core.
They may be cleared writing a “1” to the bit location.
Note: The mask bits do not prevent the status in the SIE_STAT register from being set, only from driving the INT3
line of the 8051 core high.
