Introduction
The MC68HC05X4 with on-board controller area network (CAN) module
is designed around the industry standard M68HC05 CPU core with its
familiar and efficient instruction set. The Motorola CAN module (MCAN)
is complete with line interface circuitry, comprising output drivers, input
comparators and a V_DD/2 generator. The module can handle all the
communication transactions flowing across a serial bus structure with
minimal CPU intervention. Other features of the device include a 16-bit
programmable timer, a 15-stage multi-purpose core timer and a
computer operating properly (COP) watchdog timer. The MC68HC05X4
has two modes of operation, namely single chip and bootloader mode.
This data sheet covers both the MC68HC05X4 ROM based device and
the equivalent EPROM based MC68HC705X4 device. All references in
the text to the MC68HC05X4 apply equally to the MC68HC705X4,
unless otherwise stated. References specific to the MC68HC705X4 are
italicised in the text.
