21B.7.6 Flash Memory Power Control Register (FLPWCR)
FLPWCR enables or disables a transition to the flash memory power-down mode when the LSI
switches to subactive mode * .
Note: * Subclock functions (subactive mode, subsleep mode, and watch mode) are available in the
Bit 7—Power-Down Disable (PDWND): The subactive mode is not available in versions other
than the U-mask and W-mask versions.
Only 0 should be written to this bit in the case of versions other than the U-mask and W-mask
versions.
See section 21.B.14, Flash Memory and Power-Down States, for more information.
