FRESET
0 : No operation performed
(Reset flash)
1 : Reset the flash memory
The Flash Control Register 4 (FCNT4) controls canceling program/erase operation in the middle
and initializing each status bit of Flash Status Register 2 (FSTAT2). When the FRESET bit is set to
1, program/erase operation is canceled in the middle and each status bit of FSTAT2 is initialized
(H'80).
The FRESET bit is effective only when the FENTRY bit = 1. Information on FRESET bit is ignored
unless the FENTRY bit = 1.
Make sure that when programming or erasing the flash memory, the FRESET bit remains 0.
