Figure 6. Stage shift of control transfer
Control transfer stage transition
M66290A manages control transfer sequence by H/W.
There are setup stage, data stage, and status stage in
control transfer stage, as shown in figure 6. And when
stage shifts, CTRT interrupt occurs.
There are five factors in CTRT interrupt, that is, setup
stage end, control write transfer status stage shift,
control read transfer status stage shift, control transfer
end, and control transfer sequence error. And there are
seven errors as follows in control transfer sequence
error which can be detected by H/W.
If H/W detected control transfer sequence error,
response PID is set to STALL("1x") automatically.
1. IN token packet receive in control write data stage
(In token packet receive which did not do ACK
handshake once to OUT token packet in data stage)
2. OUT token packet receive in control write status stage
3. OUT token packet receive in control read data stage.
(OUT token packet receive which did not do data transfer
once to IN token packet in data stage).
4. IN token packet receive in control read status stage.
5. Data packet receive except for Null data in control
read status stage.
6. OUT token packet receive in control write no data
status stage.
7. Data receive which exceeds maximum packet size.
In control write data stage, it can not be recognized as
sequence error when received data packet which exceeds
request wLength value.
