2. If the chip is in a mode in which the on-chip flash memory is disabled, a read will return
3. When a high level is input to the FWE pin, the initial value is H'80.
4. When a low level is input to the FWE pin, or if a high level is input and the SWE bit in
5. FLMCR1, FLMCR2, EBR, and RAMCR are 8-bit registers.
6. Bits 6 to 0 are reserved bits but are readable/writable.
* Determined by the state of the FWE pin.
Flash Memory Register Configuration
Flash Memory Register Descriptions
Flash Memory Control Register 1 (FLMCR1)
These bits are designed for the on-chip flash memory version and do not exist in the
on-chip mask ROM version.
In the on-chip mask ROM version, these bits always read 1, and writing is disabled.
H'00 and writes are invalid. Writes are also invalid when the FWE bit in FLMCR1 is not
set to 1.
FLMCR1 is 0, these registers are initialized to H'00.
Byte access must be used on these registers (do not use word or longword access).
