23.3.7.1 Timer input select register 0 (TIS0)
This register is used to select the timer input of channel 1.
By selecting the low-speed on-chip oscillator clock for the timer input, its pulse width can be measured to determine
whether the proportional relationship between the low-speed on-chip oscillator clock and the timer operation clock is
correct.
The TIS0 register can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
