Table 12.3.3.2-2 Capture Control Register (ICS01)
Bit
Function
Bit 7
ICP1:
Interrupt request
flag bit
(Input capture 1)
This bit is used as interrupt request flag for input capture 1.
“1” is written 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.
Bit 6
ICP0:
Interrupt request
flag
(Input capture 0)
This bit is used as interrupt request flag for input capture 0.
“1” is written 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.
Bit 5
ICP1:
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.
Bit 4
ICP0:
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.
Bit 3
Bit 2
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.
Bit 1
Bit 0
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.
