Bit name Function
bit7
ICP1:
Interrupt request
flag bit
(Input capture 1)
•
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.
bit6
ICP0:
Interrupt request
flag bit
(Input capture 0)
•
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.
bit5
ICE1:
Interrupt request
enable bit
(Input capture 1)
•
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.
bit4
ICE0:
Interrupt request
enable bit
(Input capture 0)
•
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.
bit3,
bit2
EG11, EG10:
Edge selection
bit
(Input capture 1)
•
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.
bit1,
bit0
EG01, EG00:
Edge selection
bit
(Input capture 0)
•
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.
