Table 19.5
• D0 to D7: Indicates the data bus which is read when the read status register command is executed.
• The FMR07 (SR5) to FMR06 bits (SR4) are set to 0 by executing the clear status register command.
• When the FMR07 bit (SR5) or FMR06 bit (SR4) is set to 1, the program and block erase command

cannot be accepted.
The status register indicates the operating status of the flash memory and whether an erasing or programming
operation completes normally or in error. Status of the status register can be read by the FMR00, FMR06, and
FMR07 bits in the FMR0 register.
Table 19.5 lists the Status Register Bits.
In EW0 mode, the status register can be read in the following cases:
The sequencer status indicates operating status of the flash memory. SR7 = 0 (busy) during auto programming
and auto erasing, and is set to 1 (ready) at the same time the operation completes.
