2. Operational Description
2.2 System Clock Controller
TMP86FH09ANG
Start the IDLE0 and SLEEP0 modes
Stop (Disable) peripherals such as a timer counter.
To start IDLE0 and SLEEP0 modes, set SYSCR2<TGHALT> to “1”.
Release the IDLE0 and SLEEP0 modes
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
of TBT and TBTCR<TBTEN>.
After releasing IDLE0 and SLEEP0 modes, the SYSCR2<TGHALT> is automatically
cleared to “0” and the operation mode is returned to the mode preceding IDLE0 and SLEEP0
modes. Before starting the IDLE0 or SLEEP0 mode, when the TBTCR<TBTEN> is set to “1”,
INTTBT interrupt latch is set to “1”.
IDLE0 and SLEEP0 modes can also be released by inputting low level on the RESET pin.
After releasing reset, the operation mode is started from NORMAL1 mode.
Note: IDLE0 and SLEEP0 modes start/release without reference to TBTCR<TBTEN> setting.
(1)
Normal release mode (IMF
EF6TBTCR<TBTEN> = “0”)
IDLE0 and SLEEP0 modes are released by the source clock falling edge, which is setting by the
TBTCR<TBTCK>. After the falling edge is detected, the program operation is resumed from the
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”.
(2) Interrupt release mode (IMF
EF6TBTCR<TBTEN> = “1”)
IDLE0 and SLEEP0 modes are released by the source clock falling edge, which is setting by the
TBTCR<TBTCK> and INTTBT interrupt processing is started.
Note 1: Because returning from IDLE0, SLEEP0 to NORMAL1, SLOW1 is executed by the asynchro-
nous internal clock, the period of IDLE0, SLEEP0 mode might be the shorter than the period set-
ting by TBTCR<TBTCK>.
Note 2: When a watchdog timer interrupt is generated immediately before IDLE0/SLEEP0 mode is
started, the watchdog timer interrupt will be processed but IDLE0/SLEEP0 mode will not be
started.
