The HC05 is a simple CPU which has no on-chip debugging
capability. Software available includes a command line Assembler, a
Windows IDE, a Register Explorer and Windows user interfaces to the
Freescale MMDS and MMEV in circuit emulators.
All 68HC08s have, built into the chip, a small software monitor (MON08)
which links to the outside world via one of the chips pins and which can be
used by developers to test programs and to program chips that contain
Flash or EEPROM. P&E provides USB interfaces to this non
standard serial protocol and a free set of development software. A production
programmer called the Cyclone PRO is also available.
These CPUs all have a special interface included on the CPU called BDM
that provides a simple debugging mechanism. P&E produce Parallel, USB
and Ethernet interfaces between the PC and this BDM (to the HC12 standard). Software
is available to support those interfaces for debugging, flash
programming and production testing. The Cyclone Pro provides both PC
based development as well as PC and standalone production programming
capabilities.
The HC11 is a simple CPU which has no on-chip debugging
capability. Software available includes a command line Assembler, a
Windows IDE, a Register Explorer and Windows user interfaces to the
Freescale MMDS in circuit emulators.
