BCSHORT
When the BCSHORT bit in the TSCUCR1 register is set to 1 (short circuit) to short-circuit between CHxB and
CHxC, there are the following restrictions:
• Skipping of period 4 is disabled (setting of the TCS4C bit in the TSCUCR2 register to 1 (the number of cycles
• When PRE measurement is turned ON and f1 is selected as the count source, the setting of period 4 is two or
The clock supply to the sensor control unit module can be stopped by setting to sensor control unit module
standby mode.
Since the clock supply to the registers in the sensor control unit is also stopped, cancel standby mode and allow
at least two cycles to elapse before changing the settings of these registers.
Perform the same processing when stopping all clocks (when setting the CM10 bit in the CM register to 1).
To initialize the sensor control unit by setting the TSCUINIT bit in the TSCUCR0 register to 1, perform the
following processing:
• Stop measurement (set the TSCUSTRT bit in the TSCUCR0 register to 0)
• No TSCU interrupt request is output (read the SIF bit in the TSCUFR register as 0) or clear the TSCU
The DTC is not initialized by performing initialization using the TSCUINIT bit.
When initializing the sensor control unit, also make the DTC settings.
Do not change clock settings while measurement is performed using the sensor control unit.
Set the CM36 bit to 0 and the CM37 bit to 0 in the CM3 register and do not switch the clock used when exiting
wait mode by an interrupt request signal.
When the sensor control unit is used in wait mode, there are the following restrictions:
• Execute the WAIT instruction or set the CM30 bit in the CM3 register to 1 immediately after the TSCUSTRT
• Set the FMR11 bit in the FMR1 register to 1 and the FMSTP bit in the FMR0 register to 0 not to stop the flash
• Do not use the sensor control unit in low-power-consumption wait mode. Set the SVC0 bit in the SVDC
