5. The program ROM area can be read with the BGO function while programming or block erasing data flash.
The suspend function halts the auto-erase operation temporarily during auto-erasure.
When auto-erasure is suspended, the next operation can be executed. (Refer to Table 30.4 Executable
Operation during Suspend.)

The clear status register command can be executed when the FST7 bit in the FST register is set to 1 (ready).
The operation of block blank check is disabled during suspend.
When suspending the auto-erasure of any block in data flash, auto-programming and reading another block
can be executed.
When suspending the auto-erasure of data flash, auto-programming and reading program ROM can be
executed.
When suspending the auto-erasure of any block in program ROM, auto-programming and reading another
block can be executed.
When suspending the auto-erasure of program ROM, auto-programming and reading data flash can be
executed.
