Start the IDLE1/2 and SLEEP1 modes
After the interrupt master enable flag (IMF) is set to "0", set the individual interrupt enable flag
(EF) to "1", which releases IDLE1/2 and SLEEP1 modes.
To start the IDLE1/2 or SLEEP1 mode, set SYSCR2<IDLE> to "1".
If the release condition is satisfied when it is attempted to start the IDLE1/2 or SLEEP1 mode,
SYSCR2<IDLE> remains cleared and the IDLE1/2 or SLEEP1 mode will not be started.
Note 1: When a watchdog timer interrupt is generated immediately before the IDLE1/2 or SLEEP1 mode
is started, the watchdog timer interrupt will be processed but the IDLE1/2 or SLEEP1 mode will
not be started.
Note 2: Before starting the IDLE1/2 or SLEEP1 mode, enable the interrupt request signals to be gener-
ated to release the IDLE1/2 or SLEEP1 mode and set the individual interrupt enable flag.

Release the IDLE1/2 and SLEEP1 modes
The IDLE1/2 and SLEEP1 modes include a normal release mode and an interrupt release mode.
These modes are selected at the interrupt master enable flag (IMF). After releasing IDLE1/2 or
SLEEP1 mode, SYSCR2<IDLE> is automatically cleared to "0" and the operation mode is returned
to the mode preceding the IDLE1/2 or SLEEP1 mode.
The IDLE1/2 and SLEEP1 modes are also released by a reset by the
RESET
pin, a power-on reset
and a reset by the voltage detection circuits. After releasing the reset, the warm-up starts. After the
warm-up is completed, the NORMAL1 mode becomes active.
• Normal release mode (IMF = "0")
The IDLE1/2 or SLEEP1 mode is released when the interrupt latch enabled by the individ-
ual interrupt enable flag (EF) is "1". The operation is restarted by the instruction that follows
the IDLE1/2 or SLEEP1 mode start instruction. Normally, the interrupt latch (IL) of the inter-
rupt source used for releasing must be cleared to "0" by load instructions.
• Interrupt release mode (IMF = "1")
The IDLE1/2 or SLEEP1 mode is released when the interrupt latch enabled by the individ-
ual interrupt enable flag (EF) is "1". After the interrupt is processed, the operation is restarted
by the instruction that follows the IDLE1/2 or SLEEP1 mode start instruction.
2.3.6.3
IDLE0 and SLEEP0 modes
The IDLE0 and SLEEP0 modes are controlled by the system control register 2 (SYSCR2) and the time
base timer control register (TBTCR). The following states are maintained during the IDLE0 and SLEEP0
modes:
• The timing generator stops the clock supply to the peripheral circuits except the time base timer.
• The data memory, the registers, the program status word and the port output latches are all held in
the states in effect before the IDLE0 or SLEEP0 mode was started.
• The program counter holds the address of the instruction 2 ahead of the instruction which starts
the IDLE0 or SLEEP0 mode.
