FT313H USB2.0 HS Host Controller Datasheet Version 1.1
Description
Note1: This is further gated by MIN_WIDTH bits
of EDGEINTC register if edge trigger interrupt is
used.
Note2: In the full-speed mode, these registers
are reserved.
-
Asynchronous Schedule Park Mode Enable
Software uses this register to enable or disable
the Park mode. When this register is set to ‘1’,
the Park mode is enabled.
-
Asynchronous Schedule Park Mode Count
This field contains a count for the number of
successive transactions that the host controller
is allowed to execute from a high-speed queue
head on the asynchronous schedule.
-
Interrupt on Asynchronous Advance
Doorbell
This bit is used as a doorbell by software to ring
the host controller to issue an interrupt at the
next advance of the asynchronous schedule.
Asynchronous Schedule Enable
This bit controls whether the host controller
skips the processing of asynchronous schedule.
0: Do not process the asynchronous schedule
1: Use the ASYNCLISTADDR register to access
the asynchronous schedule
Periodic Schedule Enable
This bit controls whether the host controller
skips the processing of the periodic schedule.
0: Do not process the periodic schedule
1: Use the PERIODICKISTBASE register to
access the periodic schedule
Frame List Size
This field specifies the size of the frame list.
00: 1024 elements (4096 bytes; default value)
01: 512 elements (2048 bytes)
10: 256 elements (1024 bytes)
11: Reserved
Host Controller Reset
This control bit is used by the software to reset
the host controller.
