12.1
The simple capture events in the dsPIC30F product
family are:
• Capture every falling edge
• Capture every rising edge
• Capture every 4th rising edge
• Capture every 16th rising edge
• Capture every rising and falling edge
These simple Input Capture modes are configured by
setting the appropriate bits ICM<2:0> (ICxCON<2:0>).
12.1.1
There are four input capture prescaler settings, speci-
fied by bits, ICM<2:0> (ICxCON<2:0>). Whenever the
capture channel is turned off, the prescaler counter will
be cleared. In addition, any Reset will clear the
prescaler counter.
12.1.2
Each capture channel has an associated FIFO buffer
which is four, 16-bit words deep. There are two status
flags which provide status on the FIFO buffer:
• ICBNE – Input Capture Buffer Not Empty
• ICOV – Input Capture Overflow
The ICBNE bit will be set on the first input capture event
and remain set until all capture events have been read
from the FIFO. As each word is read from the FIFO, the
remaining words are advanced by one position within
the buffer.
In the event that the FIFO is full with four capture
events, and a fifth capture event occurs prior to a read
of the FIFO, an overflow condition will occur and the
ICOV bit will be set to a logic ‘1’. The fifth capture event
is lost and is not stored in the FIFO. No additional
events will be captured till all four events have been
read from the buffer.
If a FIFO read is performed after the last read and no
new capture event has been received, the read will
yield indeterminate results.
12.1.3
Each capture channel can select between one of two
timers for the time base, Timer2 or Timer3.
Selection of the timer resource is accomplished
through SFR bit, ICTMR (ICxCON<7>). Timer3 is the
default timer resource available for the input capture
module.

An input capture event will generate a device wake-up
or interrupt, if enabled, if the device is in CPU Idle or
Sleep mode.

up can generate an interrupt if the conditions for
up feature is useful as a method of adding extra external
pin interrupts.
12.2.1
CPU Sleep mode allows input capture module opera-
tion with reduced functionality. In the CPU Sleep
mode, the ICI<1:0> bits are not applicable, and the
input capture module can only function as an external
interrupt source.
The capture module must be configured for interrupt
only on the rising edge (ICM<2:0> = 111) in order for
the input capture module to be used while the device
is in Sleep mode. The prescale settings of 4:1 or 16:1
are not applicable in this mode.
12.2.2
CPU Idle mode allows input capture module operation
with full functionality. In the CPU Idle mode, the interrupt
mode selected by the ICI<1:0> bits are applicable, as
well as the 4:1 and 16:1 capture prescale settings which
are defined by control bits ICM<2:0>. This mode
requires the selected timer to be enabled. Moreover, the
ICSIDL bit must be asserted to a logic ‘0’.
If
ICM<2:0> = 111 in CPU Idle mode, the input capture
pin will serve only as an external interrupt pin.
