Description
30:31 TIMEOUT_SEL
RW
R
0
Timeout Select.
'0' - Timeout check is disabled. HW clears timeout
counter.
'1' - Timeout check is enabled and HW will refer to
TIMEOUT_LENGTH as number of Tbits allowed
between header and response.
'2' - Timeout check is enabled to check header-header,
header-response, and header-header-response within
a message frame to be space within
TIMEOUT_LENGTH bit time.
'3' - invalid
For '1', HW will restart/start timeout counter after
transmitting/receiving header. HW will hold the counter
if timeout until the next header is transmitted or
received. Timeout will cause HW to stop transmission
of the current message frame together with interrupt to
SW. For receive, HW abort reception of the frame if
timeout occurs while waiting for receiving response
and notify SW with interrupt.
For '2', HW will re-start/start timeout counter after
receiving any frame bytes within a message frame.
HW will hold the counter if timeout until the IFS.
Timeout will cause HW to stop transmission of the
current message frame and notify SW with interrupt.
For receive, HW will abort reception of the message
frame if timeout occurs while waiting for receiving
response and notify SW with interrupt.
For all cases, HW stops counting when it is out of a
message frame such as IFS or CXPI bus IDLE. If the
timeout counter > TIMEOUT_LENGTH, then it will set
the INTR.TIMEOUT=1.
Note that, TIMEOUT_SEL=1/2 also enables the count
for IBS between receive header and transmit response
on top of timeout check.
TIMEOUT_DISABLED
0
Timeout check is disabled.
TIMEOUT_CHECK_BTW
_HDR_RSP
1
Timeout check is enabled and HW will refer to
TIMEOUT_LENGHT as number of Tbits allowed
between header and response.
TIMEOUT_CHECK_BTW
_HDR_HDR_RSP
2
Timeout check is enabled to check header-header,
header-response, and header-header-response within
a message frame to be space within
TIMEOUT_LENGTH bit time.
