Note 1: Standby mode selection depends on the settings of the Doze and Halt bits in the CP0's internal
Note 2: When the PLL is not used, set the LUPTM bit in the SYSCR3 register to 1 (i.e., select 2
Note3: The WURT1-WUPT0 bitys in the SYSCR2 must be not be changed during the oscillator warm-up
Note 4: Do as follows to change the operating mode immediately after the device has warmed up from the

If the Doze bit = 1, the device will always enter IDLE mode.

It is possible to move to SLOW mode immediately after the device has warmed up from STOP or SLEEP
mode.
Before moving to SLOW mode, ensure that the warm-up end flag (i.e., the WUEF bit in the SYSCR0
register) is cleared and wait for five or more instructions to complete.
• When the oscillator warm-up time (SYSCR2<WUPT1:0>) is programmed as “01” (i.e., 2
• When the oscillator warm-up time (SYSCR2<WUPT1:0>) is programmed as “10” (2
Before moving to the next operating mode, ensure that the lock-up bit, LUPFG, in the SYSCR3
register has been cleared to zero and wait for five or more instructions to complete (including the
instruction to check the LUPFG flag).
It is possible to move to NORMAL mode immediately after the device has warmed up. However, to
move to another mode after that, ensure that the lock-up bit, LUPFG, in the SYSCR3 register has been
cleared to zero and wait for five or more instructions to complete (including the instruction to check the
LUPFG flag).
