3.6 CAN Physical Interface
There is a CAN physical interface supplied on the M68EVB912D60. The CAN physical interface comprises a
Philips PCA82C250 CAN Interface controller (U1). The TXD and RXD pins on the PCA82C250 are connected to
the CANTX and CANRX pins on the MC68HC912D60 respectively. The CAN bus signals, CANH and CANL are
available on jumper J1. Table 3-1 shows the pinout for J1.
3.7 Programming Operation
It is possible to configure the M68EVB912D60 as a programming tool. To do this the relevant programming
adapter board has to be purchased (contact Motorola for further details). To configure the EVB as a programming
tool, the adapter board has to be connected to the header strips on the EVB (when doing this care should be
taken to ensure that the adapter board is installed with the correct polarity as failure to do so could result in
damage to the device being programmed). It is also necessary to install the jumpers on header P8 in the PGMR
position.
There are two possible ways of supplying the flash EEPROM programming voltage V
MAX662 chargepump I.C. (U5), or via the SDI cable. The source of the flash EEPROM programming voltage can
be selected via jumper J17.
There is an option for controlling the operation of the chargepump I.C. (U5). If there is no jumper link installed on
Jumper J14, then the V
will be supplied to the V
the operation of the chargepump I.C. via a port pin of their choice. To do this the user must connect a wire
between the pad situated to the right hand side of Jumper J14 and the pad of the port pin they want to use as the
controller. When this option is chosen the user must remove the jumper link from jumper J14.
3.8 Jumper Configuration
