・ Flash Memory Control Registers
・ Conversion Accuracy of the AD Converter
a program that accesses these registers operates differently between mask ROM and flash products. If you
use a flash product to check the operation of a program written for a mask ROM product, be sure not to write
instructions that access these registers in the program.
below. When developing your application system, careful consideration must be given to these accuracy
differences.
Mask ROM products do not contain the flash memory control registers shown in the table below. Therefore,
The conversion accuracy of the AD converter differs between mask ROM and flash products, as shown
