See Section 7.2.3 "Low Speed Time Base Register Control Register (LTBCCON)".
[ ] Enable the high-speed clock (HSCLK) when using the virtual frequency adjustment mode.
[ ] It takes max. two clocks of low-speed clock (LSCLK) from the timing of write the TBRUN bit to the
timing of start or stop the operation.
[ ] When using the on-chip debug function, the TBCOUT1 output stops during break status even if the
item "Low-speed Time Base Counter" is chosen for continuing the operation during the break status on
the debugger.
See Section 7.2.4 "Simplified RTC Time Base Counter register (LTBRR)".
[ ] LTBRR register is uninitialized except for the Power-On-Reset. Initialize by writing arbitrary data if
needed.
[ ] The simplified RTC interrupt may occur depending on a write timing to the LTBRR. Do not perform the
write operation to the LTBRR while the simplified RTC is running.
[ ] When the high-speed clock is used for the system clock, read the LTBRR register twice to verify the
data to prevent reading uncertain data while counting-up.
See Section 7.2.6 "Low Speed Time Base Counter Interrupt Selection Register (LTBINT)".
[ ] A time base counter interrupt may occur depending on a write timing to the LTBINTL or LTLBINTH.
See the program example for initializing described in "7.3.1 Operation of the Low-speed Time Base
Counter".
See Section 7.3.1 "Low-speed Time Base Counter Operation".
[ ] After writing to the LTBR register, the time by which the first low-speed time base counter interrupt
request is generated is not guaranteed. If measuring the time using the low-speed time base counter
interrupt, do so with reference to the interrupt generation interval.
[ ] The time equivalent to max. one clock of the system clock is required to reset the counter after writing
to the LTBR register.
See Section 7.3.2 "Low-speed Time Base Counter Frequency Adjustment Function".
[ ] The frequency adjustment accuracy does not guarantee the accuracy including the frequency variation
of the low-speed oscillation (32.768 kHz) due to temperature variations.
Chapter 8 16bit Timer
See Section 8.1.2 "Configuration".
[ ] When the 16-bit timer is used as two channels of 8-bit timer, the same clock settings and interrupts are
applied.
[ ] In the 8-bit timer mode, the TMHnOUT outputs the comparison result of the upper side ("TMHnDH"
and "TMHnCH").
[ ] Choose the 16-bit timer mode when using the 16-bit timer DMA request or SA-ADC trigger.
See Section 8.2.2 "16-Bit Timer n Data Register (TMHnD: n = 0 to 7)".
[ ] Set TMHnD when the 16-bit timer n is stopped (THnSTAT/THnHSTAT bits of TMHSTAT register are
"0").
[ ] When "0x0000" is written in TMHnD in the 16-bit timer mode, "0x0001" is set in TMHnD.
[ ] When "0x00" is written in TMHnDL/TMHnDH in the 8-bit timer mode, "0x01" is set in
TMHnDL/TMHnDH.
See Section 8.2.4 "16-Bit Timer n Mode Register (TMHnMOD: n = 0 to 7)".
[ ] Input the pulse for the external trigger with the width of two timer clocks or longer.
[ ] Set TMHnMOD when the timer n is stopped(THnSTAT/THnHSTAT bits of TMHSTAT register are "0").
If it is changed while it is operating, the operation is not guaranteed.
[ ] In the 8-bit timer mode, the operation mode specified by THnCS0 to 1, THnDIV2 to 0 and THnOST are
common for both upper side and lower side of the timer.
See Section 8.2.5 "16-Bit Timer n Interrupt Status Register (TMHnIS: n = 0 to 7)".
[ ] When the THnHIS bit or the THnLIS bit is "1", the interrupt request in the same channel of 8bit timer
does not activate. Clear the THnHIS bit or the THnLIS bit by writing "1" to the same number of bit in the
TMHnIC register.
