The following items should be considered when using a derivative (Table 0-1):
• Registers
– Do not write or read CAN0 registers (after reset: address range $0140 - $017F), if using a
derivative without CAN0.
– Do not write or read CAN1registers (after reset: address range $0180 - $01BF), if using a
derivative without CAN1.
– Do not write or read CAN2 registers (after reset: address range $01C0 - $01FF), if using a
derivative without CAN2.
– Do not write or read CAN3 registers (after reset: address range $0200 - $023F), if using a
derivative without CAN3.
– Do not write or read CAN4 registers (after reset: address range $0280 - $02BF), if using a
derivative without CAN4.
– Do not write or read BDLC registers (after reset: address range $00E8 - $00EF), if using a
derivative without BDLC.
• Interrupts
– Fill the four CAN0 interrupt vectors ($FFB0 - $FFB7) according to your coding policies for
unused interrupts, if using a derivative without CAN0.
– Fill the four CAN1 interrupt vectors ($FFA8 - $FFAF) according to your coding policies for
unused interrupts, if using a derivative without CAN1.
– Fill the four CAN2 interrupt vectors ($FFA0 - $FFA7) according to your coding policies for
unused interrupts, if using a derivative without CAN2.
– Fill the four CAN3 interrupt vectors ($FF98 - $FF9F) according to your coding policies for
unused interrupts, if using a derivative without CAN3.
– Fill the four CAN4 interrupt vectors ($FF90 - $FF97) according to your coding policies for
unused interrupts, if using a derivative without CAN4.
– Fill the BDLC interrupt vector ($FFC2, $FFC3) according to your coding policies for unused
interrupts, if using a derivative without BDLC.
• Ports
– The CAN0 pin functionality (TXCAN0, RXCAN0) is not available on port PJ7, PJ6, PM5,
PM4, PM3, PM2, PM1 and PM0, if using a derivative without CAN0.
– The CAN1 pin functionality (TXCAN1, RXCAN1) is not available on port PM3 and PM2, if
using a derivative without CAN1.
– The CAN2 pin functionality (TXCAN2, RXCAN2) is not available on port PM5 and PM4, if
using a derivative without CAN2.
– The CAN3 pin functionality (TXCAN3, RXCAN3) is not available on port PM7 and PM6, if
using a derivative without CAN3.
