![]() Of FOSC as determined by the Timer1 prescaler. When the internal clock source is selected the TMR1H:TMR1L register pair will increment on multiples When the external clock source is selected, the timer may operate either as a timer or a counter.Ĭlock pulses in the counter mode can be synchronized with the microcontroller internal clock or run asynchronously. When using an external clock source, a 32.768 kHz crystal can be employed. You can choose the clock source for Timer1 using the TMR1CS and T1OSCEN bits in the T1CON register. Gate Event Interrupt: An interrupt can be generated upon the completion of a gate event.īelow is the functional block diagram for your reference.Gate Value Status: You can read the current level of the gate control value.Gate Single-pulse mode: It can capture a single-pulse gate event.Gate Toggle mode: Timer1 can be configured to toggle between states when counting.Selectable Gate Source Polarity: You can choose the polarity of the gate source.Special Event Trigger (with CCP): It can generate a special event trigger when used with CCP modules.Time base for the Capture/Compare function: Timer1 can be used as a time base for Capture/Compare functions.Wake-up on overflow (external clock, Asynchronous mode only): In asynchronous mode, Timer1 overflow can wake up the processor.Interrupt on overflow: An interrupt can be triggered when Timer1 overflows.Multiple Timer1 gate (count enable) sources: Timer1 can be controlled by various sources, allowing flexibility in counting.32 kHz secondary oscillator circuit: Timer1 uses a low-power secondary oscillator circuit, often coupled with a 32.768 kHz external crystal, for precise timing.2-bit prescaler: Timer1 supports four prescaler options (1:1, 1:2, 1:4, 1:8) to divide the clock input.Programmable internal or external clock source: You can choose between internal and external clock sources for Timer1.16-bit timer/counter register pair (TMR1H:TMR1L): This pair of registers is responsible for counting and storing the timer value. ![]() It can operate in Timer mode and Counter mode and offers a range of features that make it a versatile tool in microcontroller programming. Timer1 is a 16-bit timer/counter in the PIC microcontroller, capable of counting up to 65535 pulses in a single cycle. In this tutorial, we will delve into configuring and using Timer1 in a PIC controller, exploring its various features and functionalities.
