CHAPTER 11 MULTIFUNCTIONAL TIMER
11.5
Multifunctional Timer Interrupt
The multifunctional timer can generate 16-bit free-run timer interrupts, 16-bit output
compare interrupts, 16-bit input capture interrupts, and waveform generator interrupts.
■ 16-bit Free-run Timer Interrupt
See Table 11.5-1 for 16-bit free-run timer interrupt control bits and interrupt causes.
Table 11.5-1 16-bit Free-run Timer Interrupt Control Bits and Interrupt Causes
Interrupt request flag bit
Interrupt request enable bit
Interrupt cause
When the 16-bit free-run timer value and compare-clear register (CPCLRH/CPCLRL) match, the timer
status register (TCCSH) ICLR: bit9 is set to "1". When interrupt requests are enabled in this state (TCCSH
register ICRE: bit8 = 1), interrupt requests are outputted to the interrupt controller.
When the timer value is "0000
When interrupt requests are enabled in this state (TCCSH register IRQZE: bit13 = 1), interrupt requests are
outputted to the interrupt controller.
