Is it possible to read data flash memory of RL78 without using a command?

Latest Updated:12/20/2013

Question:

Is it possible to read the data flash memory of the RL78 family MCUs without using the command for reading by calling the PFDL_Execute function of the type 04 data flash library for the RL78 family MCUs?

Answer:

Yes, it is possible.
Data can be directly read by CPU commands by following the procedure below to make initial settings for this purpose.

  • Write 1 to bit 0 (DFLEN) of the data flash control register (DFLCTL).

  • Wait for the setup time (*) by using, for example, a software timer.

    *The setup time differs with the mode of the main clock. For more information on the initial settings, refer to the User’s Manual: Hardware for the target device.
