RL78/D1A CHAPTER 25 SAFETY FUNCTIONS
● Timer input select else register (TISELSE)
This register is used to select the timer input of channel 5.
By selecting the internal low-speed oscillation clock for the timer input, its pulse width can be measured to determine
whether the proportional relationship between the internal low-speed oscillation clock and the timer operation clock is
correct.
The TISELSE register can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
