19.10 Acceptance Filter Support Unit (ASU)
Figure 19.18 Write/read of CiAFS Register in Word Access
The acceptance filter support unit has a function to judge valid/invalid of a received ID through table search.
The IDs to receive are registered in the data table; a received ID is stored in the CiAFS register ( i = 0, 1),
and table search is performed with a decoded received ID. The acceptance filter support unit can be used
for the IDs of the standard frame only.
The acceptance filter support unit is valid in the following cases.
Figure 19.18 shows the Write/Read of CiAFS Register in Word Access.
• When the ID to receive cannot be masked by the acceptance filter.
• When there are too many IDs to receive; it would take too much time to filter them by software.
(Example) IDs to receive: 078h, 087h, 111h
