Host n SOF/EOP Count Register [R/W]
Register Description
The Host n SOF/EOP Count register contains the SOF/EOP
Count Value that is loaded into the SOF/EOP counter. This
value is loaded each time the SOF/EOP counter counts down
to zero. The default value set in this register at power-up is
0x2EE0, which will generate a 1-ms time frame. The
SOF/EOP counter is a down counter decremented at a
12-MHz rate. When this register is read, the value returned is
the programmed SOF/EOP count value.
Host n SOF/EOP Counter Register [R]
Register Description
The Host n SOF/EOP Counter register contains the current
value of the SOF/EOP down counter. This value can be used
to determine the time remaining in the current frame.
