TMP86FS49BUG
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 operation 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
interrupt enable flag (EF). After the interrupt is generated, the program operation is resumed from the
instruction following the IDLE1/2 and SLEEP1/2 modes start instruction. Normally, the interrupt
latches (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
interrupt enable flag (EF) and the interrupt processing is started. After the interrupt is processed, the
program 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.
