Noise Filter Control Register
When MSEL = 001b, the Noise Filter Control Register, shown in Table , provides control
for the digital noise filter. A more detailed discussion of each bit follows the table.

NFEN—Noise Filter Enable
0 = Noise filter is disabled.
1 = Noise filter is enabled. Receive data is preprocessed by the noise filter.
NFCTL—Noise Filter Control
This field controls the delay and noise rejection characteristics of the noise filter. The
wider the counter the more delay that is introduced by the filter and the wider the noise
event that is filtered.
000 = 4-bit up/down counter
001 = 5-bit up/down counter
010 = 6-bit up/down counter
011 = 7-bit up/down counter
100 = 8-bit up/down counter
101 = 9-bit up/down counter
110 = 10-bit up/down counter
111 = 11-bit up/down counter
LIN Control Register
When MSEL = 010b, the LIN Control Register provides control for the LIN mode of oper-
ation. A more detailed discussion of each bit follows the table.
