CAN Status Interrupt MOb Registers - CANSIT2 and CANSIT1
CAN Bit Timing Register 1 - CANBT1
• Bits 14:0 - IEMOB14:0: Interrupt Enable by MOb
Note:
• Bit 15 – Reserved Bit
This bit is reserved for future use. For compatibility with future devices, it must be written to zero
when CANIE1 is written.
• Bits 14:0 - SIT14:0: Status of Interrupt by MOb
Note:
• Bit 15 – Reserved Bit
This bit is reserved for future use.
• Bit 7– Reserved Bit
This bit is reserved for future use. For compatibility with future devices, it must be written to zero
when CANBT1 is written.
• Bit 6:1 – BRP5:0: Baud Rate Prescaler
The period of the CAN controller system clock Tscl is programmable and determines the individ-
ual bit timing.
If BRP[5..0]=0, see
• Bit 0 – Reserved Bit
This bit is reserved for future use. For compatibility with future devices, it must be written to zero
when CANBT1 is written.
