• This bit is used as interrupt request flag for input capture 1.
• "1" is set to this bit upon detection of a valid edge of an external input pin.
• While the interrupt enable bit (ICE1) is set, an interrupt can be generated upon
detection of a valid edge.
• Writing "0" will clear this bit.
• Writing "1" has no effect.
• In read-modify-write operation, "1" is always read.
• This bit is used as interrupt request flag for input capture 0.
• "1" is set to this bit upon detection of a valid edge of an external input pin.
• While the interrupt enable bit (ICE0) is set, an interrupt can be generated upon
detection of a valid edge.
• Writing "0" will clear this bit.
• Writing "1" has no effect.
• In read-modify-write operation, "1" is always read.
• This bit is used to enable input capture interrupt request for input capture 1.
• While "1" is written to this bit, an input capture interrupt is generated when the
interrupt flag (ICP1) is set.
• This bit is used to enable input capture interrupt request for input capture 0.
• While "1" is written to this bit, an input capture interrupt is generated when the
interrupt flag (ICP0) is set.
• These bits are used to specify the valid edge polarity of an external input for input
capture 1.
• These bits are also used to enable input capture operation.
• These bits are used to specify the valid edge polarity of an external input for input
capture 0.
• These bits are also used to enable input capture operation.
