Section 26 Flash Memory
26.4 Register Descriptions
26.4.1 Registers
The registers/parameters which control flash memory when the on-chip flash memory is valid are
shown in table 26.4.
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 26.5.

Notes: 1. The bits except the SCO bit are read-only bits. The SCO bit is a programming-only bit.
(The value which can be read is always 0.)
2. The initial value of the FWE bit is 0 when the FWE pin goes low.
The initial value of the FWE bit is 1 when the FWE pin goes high.
3. The initial value at initiation in user mode or user program mode is H'00.
The initial value at initiation in user boot mode is H'AA.
