15.1.3 HcCommandStatus register (R/W: 02H/82H)
The HcCommandStatus register is a 4-byte register, and the bit allocation is given in
Table
and it also reflects 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) field 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)
field of the HcInterruptStatus register.
