HcCommandStatus register (R/W: 02H/82H)
The HcCommandStatus register is a 4-byte register, and the bit allocation is given in
Table 39
. This register is used by the HC to receive commands issued by the HCD,
and it also re
fl
ects the current status of the HC. To the HCD, it appears to be a
write
to set
register. The HC must ensure that bits written as logic 1 become set in the
register while bits written as logic 0 remain unchanged in the register. The HCD may
issue multiple distinct commands to the HC without concern for corrupting previously
issued commands. The HCD has normal read access to all bits.
The SchedulingOverrunCount (SOC)
fi
eld indicates the number of frames with which
the HC has detected the scheduling overrun error. This occurs when the Periodic list
does not complete before the End-of-Frame (EOF). When a scheduling overrun error
is detected, the HC increments the counter and sets the SchedulingOverrun (SO)
fi
eld of the HcInterruptStatus register.
