16-BIT TIMER 0/1
16-BIT TIMER 1
OVERVIEW
The 16-bit timer 1 is an 16-bit general-purpose timer/counter. Timer 1 has three operating modes, one of which
you select using the appropriate T1CON setting:
— Interval timer mode (Toggle output at T1OUT pin)
— Capture input mode with a rising or falling edge trigger at the T1CAP pin
— PWM mode (T1PWM)
Timer 1 has the following functional components:
— Clock frequency divider (fxx divided by 1024, 256, 64, 8 or 1) with multiplexer
— External clock input pin (T1CLK)
— 16-bit counter (T1CNTH/L), 16-bit comparator, and 16-bit reference data register (T1DATAH/L)
— I/O pins for capture input (T1CAP), or PWM or match output (T1PWM, T1OUT)
— Timer 1 overflow interrupt (IRQ3, vector EAH) and match/capture interrupt (IRQ3, vector E8H) generation
— Timer 1 control register, T1CON (set 1, FBH, Bank 1, read/write)
