CHAPTER 11 8/16-BIT COMPOSITE TIMER
11.2 Configuration
● 8/16-bit composite timer data register (Tn0DR/Tn1DR)
These registers are used to write the maximum value counted during interval timer operation or
PWM timer operation and to read the count value during PWC timer operation or input capture
operation.
● 8/16-bit composite timer status control register 0 (Tn0CR0/Tn1CR0)
These registers are used to select the timer operating mode and the count clock, and to enable
or disable IF flag interrupts.
● 8/16-bit composite timer status control register 1 (Tn0CR1/Tn1CR1)
These registers are used to control interrupt flags, timer output, and timer operation.
● 8/16-bit composite timer timer mode control register (TMCRn)
This register is used to select the noise filter function, 8-bit or16-bit operating mode, and signal
input to timer n0/n1 and to indicate the timer output value.
● Output controller
The output controller controls timer output. The timer output is supplied to the external pin
when the pin output has been enabled.
● Control logic
The control logic controls timer operation.
● Count clock selector
The selector selects the counter operating clock signal from different prescaler output signals
(divided machine clock signal and time-base timer output signal).
● Edge detector
The edge detector selects the edge of an external input signal to be used as an event for PWC
timer operation or input capture operation.
● Noise filter
This filter serves as a noise filter for external input signals. The filter function can be selected
from "H" pulse noise elimination, "L" pulse noise elimination, and "H"/"L"-pulse noise
elimination.
● TII0 internal pin (internally connected to the LIN-UART, only available on timer 00)
The TII0 pin serves as the signal input pin for timer 00. Nonetheless, it is connected to the
LIN-UART inside the chip. For information about how to use the pin, see "CHAPTER 14
LIN-UART". In addition, the TII0 pin for any timer other than timer 00 is internally fixed at
"0".
■ Input Clock
The 8/16-bit composite timer uses the output clock from the prescaler as its input clock (count
clock).
