NOTES:

1. RAM can be remapped to any 4-Kbyte boundary ($x000). âxâ 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). âyâ 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 $zD00â$zDFF are not externally addressable. âzâ represents the val-

ue of bits EE[3:0] in the CONFIG register.

5. EEPROM can be remapped to any 4-Kbyte boundary ($z000). âzâ represents the value contained in EE[3:0] in

the CONFIG register.
