Timer Interface Module A (TIMA)
TIMA channel
status and control
registers
(TASC0ÐTASC3)
Each of the TIMA channel status and control registers does the
following:
• Flags input captures and output compares
• Enables input capture and output compare interrupts
• Selects input capture, output compare, or PWM operation
• Selects high, low, or toggling output on output compare
• Selects rising edge, falling edge, or any edge as the active input
capture trigger
• Selects output toggling on TIMA overflow
• Selects 100% PWM duty cycle
• Selects buffered or unbuffered output compare/PWM operation
