Figure 4 Address/Data Demultiplexing
Special bootstrap mode allows special purpose programs to be entered into internal RAM. The boot-
loader program uses the SCI to read a 256-byte program into on-chip RAM at $0000 through $00FF.
After receiving the character for address $00FF, control passes to the loaded program at $0000.
Special test mode is used primarily for factory testing.
2.1 Memory Maps
Memory locations are the same for expanded multiplexed and single-chip modes. The on-board 256-
byte RAM is initially located at $0000 after reset. The 64-byte register block originates at $1000 after
reset. RAM and/or the register block can be placed at any other 4K boundary ($x000) after reset by writ-
ing an appropriate value to the INIT register. The 512-byte EEPROM is located at $B600 through $B7FF
after reset if it is enabled. The 8 Kbyte ROM is located at $E000 through $FFFF if it is enabled.
Hardware priority is built into the memory remapping. Registers have priority over RAM, and RAM has
priority over ROM. The higher priority resource covers the lower, making the underlying locations inac-
cessible.
In special bootstrap mode, a bootloader ROM is enabled at locations $BF40 through $BFFF.
In special test and special bootstrap modes, reset and interrupt vectors are located at $BFC0 through
$BFFF.
