Programmable Reload Timers Overview
(Timers 0—3
TMRx_IN
The eZ80F92 device features six Programmable Reload Timers (PRT). Each PRT contains
a 16-bit downcounter and a 16-bit reload register. In addition, each PRT features a clock
divider with four selectable taps for CLK ÷ 4, CLK ÷ 16, CLK ÷ 64, and CLK ÷ 256.
Each timer can be individually enabled to operate in either SINGLE PASS or CONTINU-
OUS mode. The timer can be programmed to start, stop, restart from the current value, or
restart from the initial value, and generate interrupts to the CPU.
Four of the Programmable Reload Timers (timers 0–3) feature a selectable clock source
input. The input for these timers can be either the system clock or the Real-Time Clock
(RTC) source. Timers 0–3 can also be used for event counting, with their inputs received
from a GPIO port pin. Output from timers 4 and 5 can be directed to a GPIO port pin.
Each of the six PRTs available on the eZ80F92 device can be controlled individually. They
do not share the same counters, reload registers, control registers, or interrupt signals.
