PIC16(L)F1503
19.0 TIMER1 MODULE WITH GATE
CONTROL
The Timer1 module is a 16-bit timer/counter with the
following features:
• 16-bit timer/counter register pair (TMR1H:TMR1L)
• Programmable internal or external clock source
• 2-bit prescaler
• Optionally synchronized comparator out
• Multiple Timer1 gate (count enable) sources
• Interrupt on overflow
• Wake-up on overflow (external clock,
Asynchronous mode only)
• Special Event Trigger
• Selectable Gate Source Polarity
• Gate Toggle mode
