Enhanced Local Bus Controller
13.4.3.4
Boot chip-select operation allows address decoding for a boot ROM before system initialization. LCS0 is
the boot chip-select output; its operation differs from other external chip-select outputs after a system reset.
When the core begins accessing memory after system reset, LCS0 is asserted initially to load a 4-Kbyte
boot block into the FCM buffer RAM, but core instruction fetches occur from the buffer RAM.
13.4.3.4.1
The boot chip-select also provides a programmable port size, which is configured during reset. The boot
chip-select does not provide write protection. LCS0 operates this way until the first write to OR0 and it
can be used as any other chip-select register after the preferred address range is loaded into BR0. After the
first write to OR0, the boot chip-select can be restarted only with a hardware reset.
