Note 1: In using a write instruction in the xxx bus write cycle, make sure that you use a write instruction of
Note 2: If a read of the flash memory (toggle operation) is to be performed after a write instruction is gener-
more than three machine cycles or arrange write instructions in such a way that they are generated at
intervals of three or more machine cycles. If a 16-bit transfer instruction is used or if write instructions
are executed at intervals of two machine cycles, the flash memory command sequence will not be
transmitted properly, and a malfunction may occur.
ated in the xth bus write cycle, instructions must be arranged in such a way that they are generated at
intervals of three or more machine cycles; machine cycles are counted from when the last xth bus
write cycle is generated to when each instruction is generated. Three NOP instructions are normally
used. If the interval between instructions is short, the toggle bit does not operation correctly.
