Memory Mapping
T89C5121 Flash ROM Version
4164G–SCR–07/06
In the products versions, the following internal spaces are defined:
•
•
•
•
The specific accesses from/to these memories are:
•
•
Table 46. RCON Register
Reset Value = XXXX 0XXXb
Three memory blocks are implemented
•
•
•
For first programming or an update, the program can be downloaded in the internal
EEPROM (and in the CRAM) from an external device:
•
•
Bootloader is program masked in ROM space.
The Hardware Byte BLJRB value is 0.
As described on page 7, after Reset, the Bootloader program is executed.
For this purpose, an In-System Programming (ISP) is supplied in a Bootloader. This

An internal serial EEPROM can be loaded from external with the application
program.
The ROM memory contains the Bootloader program. The entry point is located at
address F800h. The lower 14K Bytes between address C000h and F7FFh is, also,
used for the Bootloader program.
The CRAM is the application program memory. This memory is mapped in the
External RAM space. The bit RPS in RCON (SFR address 0D1h) is set to map the
CRAM space during MOVX instructions
Either an external EEPROM if detected
or from a host through RS232 serial communication.
