Trigger type, which shall be evaluated for this Trigger Control Block.
(The following Trigger Types can be combined in order to logically OR the Trigger Types for
one TCB)
Value Description HW
FDX_TRG_ERROR Trigger on Error
Error Specification given by
x_ErrTrg
structure
☺
FDX_TRG_EXTERNAL Trigger on External strobe. ☺
FDX_TRG_GENERIC Generic Data pattern to evaluate, described by
the
x_GenTrg
structure
☺
FDX_TRG_VL Trigger on reception of a VL = Trigger on any
received frame ☺
FDX_TRG_VL_DEFINED
1)
Trigger on reception of a frame with a defined
VL. The VL identifier must be specified in the
parameter ul_TCBEx.
☺
FDX_TRG_TIME_ABSOLUTE Trigger if received Time Tag is equal or newer
than the appointed absolute Trigger Time
FDX_TRG_TIME_DURATION Trigger on reception of a frame if the Time
Duration is expired, since the TCB becomes
active.
GNET_TRG_HW_BASED Special trigger mode for APX-GNET. All trigger
favilities are transferred to hardware. This mode
must be combined with one of the above
marked Trigger Modes. This is only cabaple for
TCB No 1 bacause for this mode only one TCB
is available. By setting up TCB 1 in this way the
The Trigger Logic of the APX-GNET Board will
automatically set up for this mode.
1)
Only applicable for APX-GNET
