ISP/IAP Flash Read Mode
The “read” mode of CMT2380F17 provides the byte read operation from flash memory to get the stored
data. The IFADRH and IFADRL point to the physical flash byte address. IFD stores the data which is read
from the flash content. It is recommended to verify the flash data by read mode after data programmed or
page erase.
Figure 28
–6 shows the flash byte read flow in ISP/IAP operation.
