19.10.6 CAN Enable Interrupt MOb Registers -
CANIE2 and CANIE1
• Bits 14:0 - IEMOB14:0: Interrupt Enable by MOb
– 0 - interrupt disabled.
– 1 - MOb interrupt enabled
Note: Example: CANIE2 = 0000 1100
b
: enable of interrupts on MOb 2 & 3.
• 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.
19.10.7 CAN Status Interrupt MOb Registers - CANSIT2 and CANSIT1
• Bits 14:0 - SIT14:0: Status of Interrupt by MOb
– 0 - no interrupt.
– 1- MOb interrupt.
Note: Example: CANSIT2 = 0010 0001
b
: MOb 0 & 5 interrupts.
• Bit 15 – Reserved Bit
This bit is reserved for future use.
19.10.8 CAN Bit Timing Register 1 - CANBT1
• 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
