8-BIT TIMER A

OVERVIEW
The 8-bit timer A is an 8-bit general-purpose timer/counter. Timer A has three operating modes, one of which you
select using the appropriate TACON setting:
—Interval timer mode (Toggle output at TAOUT pin)
—Capture input mode with a rising or falling edge trigger at the TACAP pin
—PWM mode (TAPWM)
Timer A has the following functional components:
—Clock frequency divider (fxx divided by 1024, 256, or 64 ) with multiplexer
—External clock input pin ( TACLK)
—8-bit counter (TACNT), 8-bit comparator, and 8-bit reference data register (TADATA)
—I/O pins for capture input (TACAP) or PWM or match output (TAPWM, TAOUT)
—Timer A overflow interrupt (IRQ0, vector E2H) and match/capture interrupt (IRQ0, vector E0H) generation
—Timer A control register, TACON (set 1, EDH, read/write)
