19.5.6
FLPWCR enables or disables a transition to the flash memory power-down mode when the LSI
switches to subactive mode.
Note: * An invalid register in the H8S/2623.
Bit 7—Power-Down Disable (PDWND): Enables or disables a transition to the flash memory
power-down mode when the LSI switches to subactive mode.
Bits 6 to 0—Reserved: These bits always read 0.
19.5.7
SCRX is an 8-bit readable/writable register that controls on-chip flash memory.
SCRX is initialized to H'00 by a reset and in hardware standby mode.
Bits 7 to 4—Reserved: Only 0 may be written to these bits.
