EATURES
Four independently configurable Screeners
(Acceptance Filters)
Each Screener has two 32-bit specifies:
– 32-bit Match and
– 32-bit Mask
32-bits of Mask per Screenerallows uniqueGroup
addressing per Screener
Higher layer protocols especially supported in Standard
CAN format with:
– Up to four, 11-bit ID Screeners that also Screen the
two (2) Data Bytes
– i.e.,DataFramesareScreenedbytheCANIDandby
Data Byte content
Up to eight, 11-bit ID Screeners half of which also
Screen the firstData Byte
All Screeners are changeable “on the fly”
Listen Only Mode, Self Test Mode
