ROM write
count index
Write count
index up to
present
This register stores the index value of write count of the
standard ROM (flash ROM)
*1
up to the present in 32-bit
binary. When the index value exceeds 100 thousand times,
"FLASH ROM ERROR" (error code: 1610) occurs. (The index
value will be counted even after it exceeds 100 thousand.)
*1 The write count does not equal to the index value.
(Since the maximum write count of the flash ROM has
been increased by the system, 1 is added to the index
value when the total write data size after the previous
count-up reaches about 1M byte.)
