TIMED-ACCESS PROTECTION
Selected SFR bits are critical to operation, making it desirable to protect them against an accidental write
operation. The timed-access procedure prevents errant behavior from accidentally altering bits that would seriously
affect microcontroller operation. The timed-access procedure requires that the write of a protected bit be
immediately preceded by the following two instructions:
43 of 102
MOV
MOV
0C7h, #0AAh
0C7h, #55h
Writing an AAh followed by a 55h to the timed access register (location C7h), opens a three-cycle window that
allows software to modify one of the protected bits. The protected bits are:

MEMORY ARCHITECTURE
The DS80C410 incorporates six internal memory areas:
256 Bytes of scratchpad (or direct) RAM
8kB of SRAM for Ethernet MAC transmit/receive buffer memory
64kB SRAM configurable as a combination of MOVX data memory and code memory
1kB SRAM configurable as extended stack memory or MOVX data memory
256 Bytes of RAM reserved for the CAN message centers (not available on the DS80C411)
64kB embedded ROM firmware

Buffer Size Configuration Bits
Up to 16MB of external code memory can be addressed through a multiplexed or demultiplexed 22-bit address
bus/8-bit data bus through eight available chip enables. Up to 4MB of external data memory can be accessed over
the same address/data buses through peripheral-enable signals. The DS80C410 also permits a 16MB merged
program/data memory map.
