REGISTER MAP
The register map for the MCP2510 is shown in
Table 10-1. Address locations for each register are
determined by using the column (higher order 4 bits)
and row (lower order 4 bits) values. The registers have
been arranged to optimize the sequential reading and
writing of data. Some specific control and status regis-
ters allow individual bit modification using the SPI Bit
Modify command. The registers that allow this com-
mand are shown as shaded locations in Table 10-1. A
summary of the MCP2510 control registers is shown in
TABLE 10-1: CAN Controller Register Map
