Registers

–

Do not write or read CAN0 registers (after reset: address range $0140 - $017F), if using a

derivative without CAN0 (see Table 0-1).

–

Do not write or read CAN1 registers (after reset: address range $0180 - $01BF), if using a

derivative without CAN1 (see Table 0-1).

–

Do not write or read CAN4 registers (after reset: address range $0280 - $02BF), if using a

derivative without CAN4 (see Table 0-1).

–

Do not write or read BDLC registers (after reset: address range $00E8 - $00EF), if using a

derivative without BDLC (see Table 0-1).

–

Do not write or read IIC registers (after reset: address range $00E0 - $00E7), if using a

derivative without IIC (see Table 0-1).

–

Do not write or read Byteflight registers (after reset: address range $0300 - $035F), if using a

derivative without Byteflight registers (see Table 0-1).

Interrupts

–

Fill the four CAN0 interrupt vectors ($FFB0 - $FFB7) according to your coding policies for

unused interrupts, if using a derivative without CAN0 (see Table 0-1).

–

Fill the four CAN1 interrupt vectors ($FFA8 - $FFAF) according to your coding policies for

unused interrupts, if using a derivative without CAN1 (see Table 0-1).

–

Fill the four CAN4 interrupt vectors ($FF90 - $FF97) according to your coding policies for

unused interrupts, if using a derivative without CAN4 (see Table 0-1).

–

Fill the BDLC interrupt vector ($FFC2, $FFC3) according to your coding policies for unused

interrupts, if using a derivative without BDLC (see Table 0-1).

–

Fill the IIC interrupt vector ($FFC0, $FFC1) according to your coding policies for unused

interrupts, if using a derivative without IIC (see Table 0-1).

–

Fill the four Byteflight interrupt vectors ($FFA0 - $FFA7) according to your coding policies for

unused interrupts, if using a derivative without Byteflight (see Table 0-1).

using a derivative without CAN1 (see Table 0-1).

–

The CAN4 pin functionality (TXCAN4, RXCAN4) is not available on port PJ7, PJ6, PM7,

PM6, PM5 and PM4, if using a derivative without CAN4 (see Table 0-1).
