(a)
FCNnCMMKCTLaH (a = 01, 03, 05, 07, 09, 11, 13, 15)
(b)
FCNnCMMKCTLaH (a = 02, 04, 06, 08, 10, 12, 14, 16)
(c)
FCNnCMMKCTLaW (a = 01, 03, 05, 07, 09, 11, 13, 15)
Note 1. i = [28:0]
Note
Masking is always defined by an ID length of 29 bits. If a mask is assigned to a
message with a standard ID, FCNnCMMKSSID[17:0] are ignored. Therefore,
only FCNnCMMKSSID[28:18] of the received ID are masked. The same mask
can be used for both the standard and extended IDs.
