(Input capture 0)
• This bit is used as an interrupt request flag of the input capture 1.
• This bit is set to "1" immediately when a valid edge of an external input pin is detected.
• When a valid edge is detected while the interrupt enable bit (ICE1: bit5) is set, the
interrupt is generated immediately.
• When this bit is set to "0": Clears the bit.
• Setting this bit to "1" has no effect on this bit.
• When this bit is read to a read modify write instruction, "1" is always read.
• This bit is used as an interrupt request flag of the input capture 0.
• This bit is set to "1" immediately when a valid edge of an external input pin is detected.
• When a valid edge is detected while the interrupt enable bit (ICE0: bit4) is set, the
interrupt is generated immediately.
• When this bit is set to "0": Clears the bit.
• Setting this bit to "1" has no effect on this bit.
• When this bit is read to a read modify write instruction, "1" is always read.
• This bit is used to enable an input capture interrupt request of the input capture 1.
• When the interrupt flag bit (ICP1: bit7) is set while this bit is set to "1", the input capture 1
interrupt is generated.
• This bit is used to enable an input capture interrupt request of the input capture 0.
• When the interrupt flag bit (ICP0: bit6) is set while this bit is set to "1", the input capture 0
interrupt is generated.
• These bits are used to specify the valid edge polarity of the external input for the input
capture 1.
• These bits are used also to enable an operation of the input capture 1.
• These bits are used to specify the valid edge polarity of the external input for the input
capture 0.
• These bits are used also to enable an operation of the input capture 0.
