17.22.9 Register Configuration
(1) Registers
The registers/parameters which control flash memory when the on-chip flash memory is valid are
shown in table 17.48.
To access any of the flash memory control registers except RAMER, the FLSHE bit in SYSCR2
must be set to 1 in a mode in which flash memory is enabled.
There are several operating modes for accessing flash memory, for example, read mode/program
mode.
Since the downloaded on-chip program is left in the on-chip RAM after the processing,
download and initialization are not required when the same processing is executed
consecutively.
