Programmable Reload Timers
PS019215-0910
The eZ80F91 device features four programmable reload timers. The core of each timer is a
16-bit downcounter. In addition, each timer features a selectable clock source, adjustable
prescaling and operates in either SINGLE PASS or CONTINUOUS mode.
In addition to the basic timer functionality, some of the timers support specialty modes
that performs event counting, input capture, output compare, and Pulse-Width Modulation
(PWM) generation functions. PWM mode supports four individually-configurable outputs
and a power trip function.
Each of the four timers available on the eZ80F91 device are controlled individually. They
do not share the same counters, reload registers, control registers, or interrupt signals. A
simplified block diagram of a programmable reload timer is displayed in
Each timer features its own interrupt which is triggered either by the timer reaching zero
or after a successful comparison occurs. As with the other eZ80F91 interrupts, the priority
is fully programmable.
