RL78/F13, F14
27.3.3 RAM-ECC function
The RL78/F13 and RL78/F14 have the RAM-ECC function. This function is used to detect erroneous data (bit errors),
generate interrupt requests, and retain the addresses of bit errors. If only one bit is in error, the data are corrected.
Caution The RAM-ECC function is disabled during on-chip debugging. Therefore, do not use the ECC test mode
to check the on-chip debugging operation. Even if the ECC test mode is used, bit errors are not
detected, error addresses are not stored, or an interrupt is not generated. In addition, even if the bit
error is 1 bit, the data is not corrected.
