instruction following the IDLE0 and SLEEP0 modes start instruction. Before starting the IDLE0 or
SLEEP0 mode, when the TBTCR<TBTEN> is set to “1”, INTTBT interrupt latch is set to “1”.
TBTCR<TBTCK> and INTTBT interrupt processing is started.

IDLE0 and SLEEP0 modes are released by the source clock falling edge, which is setting by the

To start IDLE0 and SLEEP0 modes, set SYSCR2<TGHALT> to “1”.
IDLE0 and SLEEP0 modes include a normal release mode and an interrupt release mode.
These modes are selected by interrupt master flag (IMF), the individual interrupt enable flag
