9.3.3 Timer input select register 1 (TIS1)
The TIS1 register selects an input source of the timer array unit 0.
The TIS17, TIS16, and TIS14 bits in the TIS1 register are used in conjunction with the real time clock to implement the
watch error correction in channels 7 and 6. When the TIS17 and TIS16 bits are set to 0 and 1 respectively, the RTC1HZ
output signal is selected for the timer input of channel 7.
When the TIS14 bit is set to 1, the RTC1HZ output signal is selected for the timer input of channel 6.
Set the TIS1 register by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.

the sync break field and the pulse width of the sync field)
1 1 Setting prohibited
TIS14 Selection of timer input used with channel 6 of timer array unit 0
0 Input signal of timer input pin (TI06)
1 RTC1HZ output signal
TIS12 Selection of timer input used with channel 5 of timer array unit 0
0 Input signal of timer input pin (TI05)
1 Input signal of timer input pin (TI03)
TIS10 Selection of timer input used with channel 4 of timer array unit 0
0 Input signal of timer input pin (TI04)
1 Input signal of timer input pin (TI03)
Cautions 1. Do not change the select bit of the timer input while inputting data to the TImn pin (m =
0, 1; n = 0 to 7).
2. When selecting the RTC1HZ output signal for the clock source of the timer input used
in channels 7 and 6 in the TAU, set the TIS17, TIS16, and TIS14 bits to 0, 1, and 1
respectively and select the RTC1HZ output signal for the timer input of channels 7 and
6.
Remark Set the TIS17 and TIS16 bits to 1 and 0 respectively and select the input signal of the RxD0 pin
before using the LIN-bus communication.
