Section 23 Flash Memory
23.8
The status register indicates the state of flash memory operation and whether erasure or
programming has ended successfully or with an error. The status register contents can be read
through the FMRDY, FMPRSF, and FMERSF bits in FLMSTR.
Table 23.7 shows the status register.
In the EW0 mode, the status register can be read with the following timing.
