CHAPTER 8 LOW-POWER CONSUMPTION MODE
8.5.3
Timebase Timer Mode
This mode causes all functions, excluding oscillation clock (HCLK), subclock (SCLK),
the timebase timer, the watch timer, and low voltage detection circuit, to stop. In this
mode, only the timebase timer, watch timer, and low voltage detection circuit, operate.
■
Switching to the Timebase Timer Mode
When 0 is written to the TMD bit of the low-power consumption mode control register (LPMCR) in the
PLL clock mode or main clock mode (CKSCR: SCM = 1), switching to the timebase timer mode occurs.
●
Data retention function
In the timebase timer mode, the contents of dedicated registers, such as accumulators, and the internal
RAM are retained.
●
Operation during an interrupt request
Writing 0 in the TMD bit of the low-power consumption mode control register (LPMCR) during an
interrupt request does not trigger a switch to the timebase timer mode.
If the CPU is not ready to accept any interrupt request, the instruction next to currently executing
instruction is executed. If the CPU is ready to accept any interrupt request, an interrupt operation
immediately branches to the interrupt processing routine.
●
Status of pins
Whether the I/O pins in the timebase timer mode retain the state they had immediately before switching to
the timebase timer mode or go to the high-impedance state can be controlled by the low-power
consumption mode control register (LPMCR: SPL).
Note:
To set the pin that is shared the peripheral function and port to the high impedance in the timebase timer
mode, disable the output of the peripheral function, then set the TMD bit of the low-power consumption
mode control register (LPMCR) to "0".
■
Return from Timebase Timer Mode
The timebase timer mode is cancelled by a reset factor or when an interrupt is generated.
●
Return by reset factor
When the timebase timer mode is cancelled by a reset factor, the mode transits to the main clock mode after
the timebase timer mode is cancelled, transiting to the reset sequence.
