Timer Interface Module B (TIMB)
NOTE: Reset the TIMB counter before writing to the TIMB counter modulo
registers.
TIMB channel
status and control
registers
(TBSC0ÐTBSC1)
Each of the TIMB 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 TIMB overflow
• Selects 100% PWM duty cycle
• Selects buffered or unbuffered output compare/PWM operation
