TJA_LIMT
This bit determines whether the JA-Limit function is enabled in the TJA.
0: Disable. (default)
1: Enable. The speed of the TJA outgoing data will be adjusted automatically if the FIFO in the TJA is 2-bit close to its full or emp-
tiness.
3
TJA_EN
This bit controls whether the TJA is enabled to use.
0: Disable. (default)
1: Enable.
2 - 1
TJA_DP[1:0]
These bits select the depth of the TJA FIFO.
00: 128-bit. (default)
01: 64-bit.
1X: 32-bit.
0
TJA_BW
This bit selects the Corner Frequency for the TJA.
0: 6.77 Hz (in E1 mode). (default)
1: 0.87 Hz (in E1 mode).
