CHAPTER 11 8/16-BIT COMPOSITE TIMER
11.14 Registers
[bit5] TIS: Timer n0 internal signal select bit
This bit selects the signal input to timer n0 when the PWC timer function or input capture function is
selected.
The functions of this bit vary among channels. Details of the functions for different channels are explained
below.
• Ch. 0
Writing "0" to this bit selects the external signal (EC0) as the signal input for timer 00.
Writing "1" to this bit selects the internal signal (TII0) as the signal input for timer 00.
The external pin assignment for the EC0 pin can be changed. For details, see "CHAPTER 29 SYSTEM
CONFIGURATION CONTROLLER".
During timer operation (T00CR1:STA = 1), the write access to this bit is invalid.
bit5
Writing "0"
Writing "1"
• Channels other than ch. 0
Writing "0" to this bit selects the external signal (ECn) as the signal input for timer n0.
Writing "1" to this bit is prohibited. Always write "0" to this bit.
bit5
Writing "0"
Writing "1"
[bit4] MOD: 8-bit/16-bit operating mode select bit
This bit selects 8-bit or 16-bit operating mode.
Writing "0" to this bit allows timers n0 and n1 to operate as separate 8-bit timers.
Writing "1" to this bit allows timers n0 and n1 to operate as a 16-bit timer.
While this bit is "1", if the timer starts operating (Tn0CR1/Tn1CR1:STA = 1) with the PWM timer function
(variable-cycle mode), this bit is automatically set to "0".
During timer operation (Tn0CR1/Tn1CR1:STA = 1), the write access to this bit is invalid.
bit4
Writing "0"
Writing "1"
[bit3:2] FE1[1:0]: Timer n1 filter function select bits
These bits select the filter function for the external signal (ECn) to timer n1 when the PWC timer function or
the input capture function is selected.
During timer operation (Tn1CR1:STA = 1), the write access to these bits is invalid.
The settings of the bits have no effect on operation when the interval timer function or the PWM timer
function is selected (the filter function does not operate.).
bit3:2
Writing "00"
Writing "01"
Writing "10"
Writing "11"
168
Selects the external signal (EC0) as the signal input for timer 00.

Setting prohibited.
Selects the 8-bit operating mode.
Selects the 16-bit operating mode.
Disables the filter function.
Filters out "H" pulse noise.
Filters out "L" pulse noise.
Filters out both "H" pulse noise and "L" pulse noise.
