You have a choice of doing your software development in the flash memory or in the static
RAM included on the OP6800. The flash memory and SRAM options are selected with
the
The advantage of working in RAM is to save wear on the flash memory, which is limited
to about 100,000 write cycles. The disadvantage is that the code and data might not both
fit in RAM.
OP6800s that are special-ordered with the 512K flash/512K SRAM memory option have
two 256K flash memories. By default, Dynamic C will use only the first flash memory for
program code in these OP6800s. Uncomment the BIOS macro
BIOS\RABBITBIOS.C
in excess of the available memory in the first flash.
