2. Operational Description
2.2 System Clock Controller
TMP86FS49BUG
(2) IDLE1 mode
In this mode, the internal oscillation circuit remains active. The CPU and the watchdog timer are
halted; however on-chip peripherals remain active (Operate using the high-frequency clock).
IDLE1 mode is started by SYSCR2<IDLE> = "1", and IDLE1 mode is released to NORMAL1
mode by an interrupt request from the on-chip peripherals or external interrupt inputs. When the IMF
(Interrupt master enable flag) is “1” (Interrupt enable), the execution will resume with the acceptance
of the interrupt, and the operation will return to normal after the interrupt service is completed. When
the IMF is “0” (Interrupt disable), the execution will resume with the instruction which follows the
IDLE1 mode start instruction.
(3) IDLE0 mode
In this mode, all the circuit, except oscillator and the timer-base-timer, stops operation.
This mode is enabled by SYSCR2<TGHALT> = "1".
When IDLE0 mode starts, the CPU stops and the timing generator stops feeding the clock to the
peripheral circuits other than TBT. Then, upon detecting the falling edge of the source clock selected
with TBTCR<TBTCK>, the timing generator starts feeding the clock to all peripheral circuits.
When returned from IDLE0 mode, the CPU restarts operating, entering NORMAL1 mode back
again. IDLE0 mode is entered and returned regardless of how TBTCR<TBTEN> is set. When IMF =
“1”, EF7 (TBT interrupt individual enable flag) = “1”, and TBTCR<TBTEN> = “1”, interrupt pro-
cessing is performed. When IDLE0 mode is entered while TBTCR<TBTEN> = “1”, the INTTBT
interrupt latch is set after returning to NORMAL1 mode.
2.2.3.2 Dual-clock mode
Both the high-frequency and low-frequency oscillation circuits are used in this mode. P21 (XTIN) and
P22 (XTOUT) pins cannot be used as input/output ports. The main system clock is obtained from the
high-frequency clock in NORMAL2 and IDLE2 modes, and is obtained from the low-frequency clock in
SLOW and SLEEP modes. The machine cycle time is 4/fc [s] in the NORMAL2 and IDLE2 modes, and
4/fs [s] (122
s at fs = 32.768 kHz) in the SLOW and SLEEP modes.
The TLCS-870/C is placed in the signal-clock mode during reset. To use the dual-clock mode, the low-
frequency oscillator should be turned on at the start of a program.
(1) NORMAL2 mode
In this mode, the CPU core operates with the high-frequency clock. On-chip peripherals operate
using the high-frequency clock and/or low-frequency clock.
(2) SLOW2 mode
In this mode, the CPU core operates with the low-frequency clock, while both the high-frequency
clock and the low-frequency clock are operated. As the SYSCR2<SYSCK> becomes "1", the hard-
ware changes into SLOW2 mode. As the SYSCR2<SYSCK> becomes “0”, the hardware changes
into NORMAL2 mode. As the SYSCR2<XEN> becomes “0”, the hardware changes into SLOW1
mode. Do not clear SYSCR2<XTEN> to “0” during SLOW2 mode.
(3) SLOW1 mode
This mode can be used to reduce power-consumption by turning off oscillation of the high-fre-
quency clock. The CPU core and on-chip peripherals operate using the low-frequency clock.
