Section 19 Controller Area Network (RCAN-ET)
Bit 0 — Bit Sample Point (BSP = BCR1[0]): Sets the point at which data is sampled. Three-time
sampling is only available when the BRP is programmed to be greater than 4.
• BCR0 (Address = H'006)
Bits 8 to 15 : Reserved. The written value should always be '0' and the returned value is '0'.
Bits 7 to 0—Baud Rate Pre-scale (BRP[7:0] = BCR0 [7:0]): These bits are used to define the
peripheral bus clock periods contained in a Time Quantum.
