FLASH status register

(1FE1H)
Note 1: If a nonmaskable interrupt occurs during a write to the FLASH, the WINT is set to "1" and the writing is
Note 2: Even if a nonmaskable interrupt occurs during an FLASH warm-up, the CPU stays at a halt until the warm-up is
Note 3: The WINT is automatically cleared to “0” when a read instruction is executed to the EEPSR register.
Note 4: When MNPWDW is changed from “0” to “1”, EWUPEN becomes “1” after taking 2
Note 5: If the BFBUSY is “1”, executing a read instruction or fetch to the FLASH area causes FFH to be read. Fetching

discontinued, and then warm-up (CPU wait) for the control circuit of Flash memory is executed. (The write data
counter is initialized.) If WINT = “1” is detected in the nonmaskable interrupt service routine, a write is not
completed successfully. So, it is necessary to try a write again. The content of the page to which a write is taking
place may be changed to an unexpected value depending on the timing when the WINT becomes “1”.
