Item
16-bit free-running
timer (FRT),
1 channel
Watchdog timer
(WDT), 1 channel
Clock pulse
generator (CPG)
Features (cont)
Specifications
Choice of four counter input clocks
Two independent comparators (allowing generation of two waveform
outputs)
Input capture (choice of rising edge or falling edge)
Counter clear specification
Four interrupt sources
Can be switched between watchdog timer mode and interval timer mode
Internal reset, external signal (WDTOVF), or interrupt generated on count
overflow
Used when standby mode is cleared or the clock frequency is changed,
and in clock pause mode
Selection of eight counter input clocks
Built-in clock pulse generator
Selection of crystal or external clock as clock source
Built-in clock-multiplication PLL circuits
Built-in PLL circuit for phase synchronization between external clock and
internal clock
CPU/DSP core clock (I ), peripheral module clock (P ), and external
interface clock (E ) frequencies can be scaled independently
Three internal clocks (P /8, P /32, P /128)
External clock (enabling external event counting)
Counter value can be cleared by compare match A
Two compare match sources (OCIA, OCIB)
One input capture source (ICI)
One overflow source (OVI)
