17.4.4 Status Register
register
Status
(1) When a given address in the user ROM area is read after writing the Read Status Register com-
(2) When a given address in the user ROM area is read after executing the Program or Block Erase
to D
The status register indicates the operating status of the flash memory and whether an erase or pro-
gramming operation terminated normally or in error. The status of the status register can be known by
reading the FMR00, FMR06, and FMR07 bits in the FMR0 register.
Table 17.5 lists the status register.
In EW0 mode, the status register can be read in the following cases:
• Sequence Status (SR7 and FMR00 Bits )
• Erase Status (SR5 and FMR07 Bits)
• Program Status (SR4 and FMR06 Bits)
Jan 27, 2006
The sequence status indicates the operating status of the flash memory. SR7 = 0 (busy) during auto
programming and auto erase, and is set to “1” (ready) at the same time the operation finishes.
Refer to Section 17.4.5, “Full Status Check.”
