– 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 and Table 0-2).

– 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 and Table 0-2).

– 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 and Table 0-2).

– 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 and Table 0-2).

• 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 (see Table 0-1 and

Table 0-2).

– The CAN1 pin functionality (TXCAN1, RXCAN1) is not available on port PM3 and PM2, if

using a derivative without CAN1 (see Table 0-1 and Table 0-2).

– 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 and Table 0-2).

– The BDLC pin functionality (TXB, RXB) is not available on port PM1 and PM0, if using a

derivative without BDLC (see Table 0-1 and Table 0-2).

– The IIC pin functionality (SCL, SCA) is not available on port PJ7 and PJ6, if using a derivative

without IIC (see Table 0-1 and Table 0-2).

– The Byteflight pin functionality (BF_PSLM, BF_PERR, BF_PROK, BF_PSYN, TX_BF,

RX_BF) is not available on port PM7, PM6, PM5, PM4, PM3 and PM2, if using a derivative

without Byteflight (see Table 0-1 and Table 0-2).

– Do not write MODRR1 and MODRR0 Bit of Module Routing Register (PIM_9DTB128 Block

User Guide), if using a derivative without CAN0 (see Table 0-1 and Table 0-2).

– Do not write MODRR3 and MODRR2 Bit of Module Routing Register (PIM_9DTB128 Block

User Guide), if using a derivative without CAN4 (see Table 0-1 and Table 0-2).

• Pins not available in 80 pin QFP package for MC9S12DG128E, MC9S12DG128,

MC9S12DJ128E, MC9S12DJ128, MC9S12A128, SC515847, and SC515848

– Port H

In order to avoid floating nodes the ports should be either configured as outputs by setting the

data direction register (DDRH at Base+$0262) to $FF, or enabling the pull resistors by writing

a $FF to the pull enable register (PERH at Base+$0264).

– Port J[1:0]

Port J pull-up resistors are enabled out of reset on all four pins (7:6 and 1:0). Therefore care must

be taken not to disable the pull enables on PJ[1:0] by clearing the bits PERJ1 and PERJ0 at

Base+$026C.
