Bit

Initial value

Read/Write

PDWND

R/W

—

FLPWCR enables or disables a transition to the flash memory power-down mode when the LSI

switches to subactive mode. The power supply circuit can be read in the subactive mode, although

it is partly halted in the power-down mode.

Bit 7—Power-down Disable (PDWND)

This bit selects the power-down mode of the flash memory when a transition to the subactive

mode is made.

Bit 7

PDWND

Description

When this bit is 0 and a transition is made to the subactive mode, the flash memory

enters the power-down mode.

(initial value)

When this bit is 1, the flash memory remains in the normal mode even after a

transition is made to the subactive mode.

Bits 6 to 0—Reserved

These bits are always read as 0 and cannot be modified.
