7.1 Program Memory
The Program Memory of the P8xCE598 consists of 32 kbytes ROM on-chip, externally expandible up to 64 kbytes.

Notes
1. This implementation prevents reading of the internal program code by switching from external Program Memory
during a MOVC instruction.
2. By setting a security bit the internal Program Memory content is protected, which means it cannot be read out.
If the security bit has been set to LOW there are no restrictions for the MOVC instruction.
7.2 Internal Data Memory
The internal Data Memory is physically built-up and accessible as shown in Table 4 (see Fig.5).

Notes
1. MAIN RAM can be addressed directly and indirectly as in the 80C51.
2. AUXILIARY RAM (0 to 255):
a) Is indirectly addressable in the same way as the external Data Memory with MOVX instructions.
b) Access will not affect the ports P0, P2, P3.6 and P3.7 during internal program execution.
3. SFRs = Special Function Registers.
