325 / 410 page  Page 311 TMP89FS60 RA003 Figure 21-2 Show/Hide Switching for BOOTROM and RAM 21.2.5 Flash memory standby control (FLSSTB<FSTB>) When the TMP89FS60 does not access the flash memory, a steady-state current of flash memory can be cut off to decrease the electric energy consumed. In IDLE0, IDLE1, IDLE2, SLEEP0, SLEEP1, and STOP modes, a steady-state current is automatically cut. In SLOW1 mode, a steady-state current can be cut by controlling registers, on the condition that the flash mem- ory is not accessed to execute a program on RAM. To cut a steady-state current being supplied to the flash mem- ory, set FLSSTB<FSTB> to "1" by using a control program allocated to RAM (if FLSSTB<FSTB> is configured using a control program allocated to the flash memory, the configured value will be invalidated).
