Start the IDLE1/2 and SLEEP1/2 modes

After IMF is set to "0", set the individual interrupt enable flag (EF) which releases IDLE1/2

and SLEEP1/2 modes. To start IDLE1/2 and SLEEP1/2 modes, set SYSCR2<IDLE> to “1”.

・

Release the IDLE1/2 and SLEEP1/2 modes

IDLE1/2 and SLEEP1/2 modes include a normal release mode and an interrupt release

mode. These modes are selected by interrupt master enable flag (IMF). After releasing

IDLE1/2 and SLEEP1/2 modes, the SYSCR2<IDLE> is automatically cleared to “0” and the op-

eration mode is returned to the mode preceding IDLE1/2 and SLEEP1/2 modes.

IDLE1/2 and SLEEP1/2 modes can also be released by inputting low level on the RESET

pin. After releasing reset, the operation mode is started from NORMAL1 mode.

(1)

Normal release mode (IMF = “0”)

IDLE1/2 and SLEEP1/2 modes are released by any interrupt source enabled by the individual inter-

rupt enable flag (EF). After the interrupt is generated, the program operation is resumed from the in-

struction following the IDLE1/2 and SLEEP1/2 modes start instruction. Normally, the interrupt latch-

es (IL) of the interrupt source used for releasing must be cleared to “0” by load instructions.

(2)

Interrupt release mode (IMF = “1”)

IDLE1/2 and SLEEP1/2 modes are released by any interrupt source enabled with the individual in-

terrupt enable flag (EF) and the interrupt processing is started. After the interrupt is processed, the pro-

gram operation is resumed from the instruction following the instruction, which starts IDLE1/2 and

SLEEP1/2 modes.

Note:When a watchdog timer interrupts is generated immediately before IDLE1/2 and SLEEP1/2

modes are started, the watchdog timer interrupt will be processed but IDLE1/2 and

SLEEP1/2 modes will not be started.
