23.3
Flash memory is controlled by the pins as shown in table 23.3.
Table 23.3 Pin Configuration
23.4
23.4.1
The registers/parameters which control flash memory when the on-chip flash memory is valid are
shown in table 23.4.
There are several operating modes for accessing flash memory, for example, read mode/program
mode.
There are two memory MATs: user MAT and user boot MAT. The dedicated registers/parameters
are allocated for each operating mode and MAT selection. The correspondence of operating modes
and registers/parameters for use is shown in table 23.5.
