Timers
multifunction, multipurpose timers
– Input capture, output compare, auto
– 2-phase encoder with up/down count
– Suitable for motor control apps
– Counts events even when system clock
pendent RC circuit for greater safety
Modulation (PWM) timer with
ripple-reduction feature
– Can be used as a D/A converter by
minutes, hours, days and weeks
stored in memory and generated on
output pins with the PPG or TPC in
conjunction with a timer and DMA
outputs using TPU as base
in 4-bit groups
simultaneously and independently
parallel with DTC and DMAC
