Description
Filter match index
This register contains the index corresponding to the received identifier. It can be used to directly
write or read the data in SRAM (see Section 23.8.2.2, Slave mode for more details).
When no filter matches, IFMI[0:4] = 0. When Filter n is matching, IFMI[0:4] = n + 1.
23.7.2.19 Identifier filter mode register (IFMR)
This register is not implemented on LINFlex_1.
Address: Base + 0x0048
