Timer 3

Timer 3 can function as timer or counter. When functioning as a timer, Timer 3 is incremented in periods based

on the system clock. When functioning as a counter, Timer 3 is incremented in response to a 1-to-0 transition

(falling edge) at its respective input. Timer 3 can be configured in four different operating modes to use in a variety

of applications, see Table 8.

Operation

13-Bit Timer

The timer is essentially an 8-Bit counter with a divide-by-32 prescaler. This mode is

included solely for compatibility with Intel 8048 devices.

16-Bit Timer

The timer registers, TLx and THx, are concatenated to form a 16-Bit counter.

16-Bit Timer

The timer registers, TLx and THx, are concatenated to form a 16-Bit counter, which is

triggered by the PWM Unit to enable a single shot measurement on a preset channel with

the measurement unit.

16-Bit Timer

The timer registers, TLx and THx, are concatenated to form a 16-Bit counter, which is

triggered by the PWM Unit to enable the LIN Baudrate Measurement.

8-Bit Timer with Auto-reload

The timer register TLx is reloaded with a user-defined 8-Bit value in THx upon overflow.

Timer 3 operates as Two 8-Bit Timers

The timer registers, TL3 and TH3, operate as two separate 8-Bit counters.

Timer 3 operates as Two 8-Bit Timers

The timer registers, TL3 and TH3, operate as two separate 8-Bit counters. In this mode the

100 kHz Low Power Clock can be measured. TL3 acts as an edge counter for the clock

edges and TH3 as an counter which counts the time between the edges.
