Figure 6. Stage shift of control transfer
Control transfer stage transition
M66290A manages control transf er sequence by H/W.
There are setup stage, data stage, and status stage in
control transf er stage, as shown in f igure 6. And when
stage shif ts, CTRT interrupt occurs.
There are f iv e f actors in CTRT interrupt, that is, setup
stage end, control write transf er status stage shif t,
control read transf er status stage shif t, control transf er
end, and control transf er sequence error. And there are
sev en errors as f ollows in control transf er sequence
error which can be detected by H/W.
If H/W detected control transf er sequence error,
response PID is set to STALL("1x") automatically.
1. IN token packet receiv e in control write data stage
(In token packet receiv e which did not do ACK
handshake once to OUT token packet in data stage)
2. OUT token packet receiv e in control write status stage
3. OUT token packet receiv e in control read data stage.
(OUT token packet receiv e which did not do data transf er
once to IN token packet in data stage).
4. IN token packet receiv e in control read status stage.
5. Data packet receiv e except f or Null data in control
read status stage.
6. OUT token packet receiv e in control write no data
status stage.
7. Data receiv e which exceeds maximum packet size.
In control write data stage, it can not be recognized as
sequence error when receiv ed data packet which exceeds
request wLength v alue.
