o
Flash Memory Sectors FS0-1 will be mapped from 8000-FFFFH in the Combined
Space Mode (in both Program Space and Data Space). Bits 2 and 4 of the VM Register
are set to 1.
o
EEPROM Sectors EES0-1 will be mapped in the Program Space from 0000H-3FFFH.
EEPROM Sectors EES2-3 will be mapped in the Data Space from 0000H-3FFFH.
Bits 1 and 3 of the VM Register are set to 1.
o
SRAM will be mapped in the Data Space from 4000-47FFH. Bit 0 of the VM Register
is set to 0.
The Abel equations in PSDsoft will be as followed:
FS0
= (Address>= ^h8000) & (Address<=^hBFFF);
FS1
= (Address>= ^hC000) & (Address<=^hFFFF);
EES0 = (Address>= ^h0000) & (Address<=^h1FFF) & !PSEN;
EES1 = (Address>= ^h2000) & (Address<=^h3FFF) & !PSEN;
EES2 = (Address>= ^h0000) & (Address<=^h1FFF) & PSEN;
EES3 = (Address>= ^h2000) & (Address<=^h3FFF) & PSEN;
RS0
= (Address>= ^h4000) & (Address<=^h47FF);

Table 14. VM Register Contents in the 80C31 Memory Map Example
When the microcontroller reads the VM register, the contents read back are shown in
Table 14. The VM Register content at power up is specified in PSDsoft.
