6.3.8 Timer input select register 0 (TIS0)
The TIS0 register is used to select the channel 1 timer input.
The TIS0 register can be set by an 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
Figure 6-17. Format of Timer Input Select register 0 (TIS0)
Address: F0074H After reset: 00H R/W
Symbol 7 6 5 4 3 2 1 0
TIS0 0 0 0 0 0 TIS02 TIS01 TIS00
TIS02 TIS01 TIS00 Selection of timer input used with channel 1
0 0 0 Input signal of timer input pin (TI01)
1 0 0 Low-speed on-chip oscillator clock (fIL)
1 0 1 Subsystem clock (fSUB)
Other than above Setting prohibited
Caution High-level width, low-level width of timer input is selected, will require more than 1/f
MCK +10
ns.
Therefore, when selecting f
SUB to fCLK (CSS bit of CKS register = 1), can not TIS02 bit set to 1.
6.3.9 Timer output select register (TOS)
The TOS register is used to enable the remote control output function.
Remote control output are generated by using the PWM output signal generated by channels 2 and 3 (mask wave) to
mask the PWM output signal generated by channels 6 and 7 (carrier wave).
Rewriting the TOS register is only possible before counting starts (TE02, TE03, TE06, TE07 = 0).
The TOS register can be set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.

Address: F0079H After reset: 00H R/W
Symbol 7 6 5 4 3 2 1 0
TOS 0 0 0 0 0 0 0 TOS0
TOS0 Remote control output setting
0 Disable (channels 2, 3, 6, and 7 is used for timer output)
1 Enable (remote control output to the TO03 pin)
Cautions 1. Channels 2, 3, 6, and 7 cannot be used for any other function when remote control output
is enabled (TOS0 = 1).
2. Do not set the TOS0 bit to 1 in 32-pin products.
