Timer Interface Module A (TIMA)
25.8.4 TIMA Channel Status and Control Registers
Each of the TIMA channel status and control registers:
• 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 0% and 100% PWM duty cycle
• Selects buffered or unbuffered output compare/PWM operation
