Interrupt Status Register, Address [Address = 0Dh]. The Interrupt Status register is a READ/WRITE register providing
interrupt status. Interrupts are cleared by writing to this register. To clear a specific interrupt, the register is written with corre-
sponding bit set to ’1’.
Current Data Set Register/Hardware Revision/SOF Counter LOW [Address = 0Eh]. This register has two modes. Read
from this register indicates the current SL811HS silicon revision.
Writing to this register sets up auto generation of SOF to all connected peripherals. This counter is based on the 12 MHz clock
and is not dependent on the crystal frequency. To set up a 1 ms timer interval, the software must set up both SOF counter registers
to the proper values.

D+
Value of the Data+ pin.
Bit 7 provides continuous USB Data+ line status. Once it is determined that a device
is inserted (as described below) with bits 5 and 6, bit 7 is used to detect if the inserted
device is low speed (0) or full speed (1).
6
Device Detect/Resume Device Detect/Resume Interrupt.
Bit 6 is shared between Device Detection status and Resume Detection interrupt.
When bit-6 of register 05h is set to one, this bit is the Resume detection Interrupt bit.
Otherwise, this bit is used to indicate the presence of a device, ’1’ = device ‘Not present’
and ’0’ = device ‘Present.’ In this mode, check this bit along with bit 5 to determine
whether a device has been inserted or removed.
5
Insert/Remove
Device Insert/Remove Detection.
Bit 5 is provided to support USB cable insertion/removal for the SL811HS in host mode.
This bit is set when a transition from SE0 to IDLE (device inserted) or from IDLE to
SE0 (device removed) occurs on the bus.

‘1’ = Interrupt on SOF Timer.
