Note:
IDPROG (F078h / 3Ch)
Table 59.
All identification words are read only registers.
The values written inside different Identification Register bits are valid only after the Flash
initialization phase is completed. When code execution is started from internal memory (pin
EA held high during reset), the Flash has certainly completed its initialization, so the bits of
Identification Registers are immediately ready to be read out. On the contrary, when code
execution is started from external memory (pin EA held low during reset), the Flash
initialization is not yet completed, so the bits of Identification Registers are not ready. The
user can poll bits 15 and 14 of IDMEM register: when both bits are read low, the Flash
initialization is complete, so all Identification Register bits are correct.
Before Flash initialization completion, the default setting of the different Identification
Registers are the following:
