Introduction
This application note documents differences between 68HC908MR24 (MR24) 68HC908MR32 (MR32). information intended help users migrate from MR24 MR32. features MR32 differences between are: MR32 Kbytes FLASH memory; MR24 Kbytes FLASH. FLASH programming block protection schemes different MR32 MR24. FLASH memory low-power mode been added MR32. break module been added MR32 used user software debug. MR32 optional, user-enabled, low-power STOP instruction. Monitor mode enhancements MR32 initial FLASH memory programming.

Freescale Semiconductor, Inc. Application Note Background
68HC908MR32 improved version 68HC908MR24 launched enhance Motorola's family products designed motor control applications. MR32 mechanical drop-in replacement MR24. From software point view, MR24 MR32 have address differences. These address changes primarily revolve around FLASH memory array. Table shows thumbnail sketch functional address differences between devices. Table MR24 MR32 Functional/Address Differences

Application Note From Hardware Point View
From Hardware Point View
physical footprint MR32 same that MR24. MR24's FLASH memory module been replaced MR32 with memory module that designed differently. Because that change, FLASH control registers reside different addresses. example, MR24, erased FLASH reads logic programmed reads logic MR32, erased FLASH reads logic programmed reads logic MR32 will enter monitor mode when reset vector ($FFFE-$FFFF) erased, eliminating requirement applying input specific logic levels three port pins. This feature simplifies initial in-circuit programming device. break module been added MR32. primary purpose software debug. break module generate break interrupt that stops normal program flow defined address enter background program.

From Software Point View
number control data register addresses have changed from MR24 MR32. convenience, input/output (I/O) include files MR32 both assembler languages included this application note. MR24, STOP instruction disabled (central processor unit) mask option register (MOR) used. low-power STOP instruction been added MR32. This instruction enabled setting write-once MOR. default STOP instruction STOP disabled. addition break module MR32 primarily development tools. also accessible users allowing break upon address match possible debugging programs.

Features break module include: Accessible registers during break interrupt CPU-generated break interrupts Software-generated break interrupts disabling during break interrupts
Freescale Semiconductor, Inc.
When internal address matches value written break address registers, break module issues breakpoint signal CPU. then loads instruction register with software interrupt instruction (SWI) after completion current instruction. program counter vectors $FFFC $FFFD ($FEFC $FEFD monitor mode). Either these events cause break interrupt occur: CPU-generated address (the address program counter) matches contents break address registers. Software writes logic BRKA break status control register.
When CPU-generated address matches contents break address registers, break interrupt begins after completes current instruction. return-from-interrupt instruction (RTI) break routine ends break interrupt returns normal operation.
Address Changes
addresses listed here have changed from MR24 MR32, while remainder status/control addresses stayed same. bits within these registers also remain same. addresses status/control addresses MR32 listed here.
