NOTES:
1. RAM can be remapped to any 4-Kbyte boundary ($x000). "x" represents the value contained in RAM[3:0] in the
INIT register.
2. The register block can be remapped to any 4-Kbyte boundary ($y000). "y" represents the value contained in
REG[3:0] in the INIT register.
3. Special test mode vectors are externally addressed.
4. In special test mode the address locations $zD00—$zDFF are not externally addressable. "z" represents the val-
ue of bits EE[3:0] in the CONFIG register.
5. EEPROM can be remapped to any 4-Kbyte boundary ($z000). "z" represents the value contained in EE[3:0] in
the CONFIG register.
