8.5
The input capture module is useful in applications
requiring frequency (period) and pulse measurement.
The dsPIC33F devices support up to eight input
capture channels.
The input capture module captures the 16-bit value of
the selected time base register when an event occurs
at the ICx pin. The events that cause a capture event
are listed below in three categories:
1.
2.
3.
Each input capture channel can select between one of
two 16-bit timers (Timer2 or Timer3) for the time base.
The selected timer can use either an internal or an
external clock.
Other operational features include:
• Device wake-up from capture pin during CPU
• Interrupt on input capture event
• 4-word FIFO buffer for capture values
• Input capture can also be used to provide
Input capture channels IC1 and IC2 support DMA data
transfers.
8.6
in applications that require controlled timing pulses or
PWM modulated pulse streams.
The output compare module has the ability to compare
the value of a selected time base with the value of one
or two compare registers (depending on the operation
mode selected). Furthermore, it has the ability to
generate a single output pulse, or a repetitive
sequence of output pulses, on a compare match event.
Like most dsPIC33F peripherals, it also has the ability
to generate interrupts on compare match events.

Output Compare/PWM Module
Preliminary
The dsPIC33F device may have up to eight output
compare channels, designated OC1 through OC8.
Refer to the specific device data sheet for the number
of channels available in a particular device. All output
compare channels are functionally identical.
Each output compare channel can use one of two
selectable time bases. The time base is selected using
the OCTSEL bit (OCxCON<3>). An ‘x’ in the pin,
register or bit name denotes the specific output
compare channel. Refer to the device data sheet for the
specific timers that can be used with each output
compare channel number.
Each output compare module has the following modes
of operation:
• Single Compare Match mode
• Dual Compare Match mode generating
• Simple Pulse-Width Modulation mode
Output compare channels, OC1 and OC2, support
DMA data transfers.
8.7
The dsPIC33F Data Converter Interface (DCI) module
allows simple interfacing to devices such as audio
coder/decoders (codecs), A/D Converters and D/A
Converters.
The following interfaces are supported:
• Framed Synchronous Serial Transfer (Single or
• Inter-IC Sound (I
• AC-Link (AC’97) Compliant mode
Many codecs intended for use in audio applications
support sampling rates between 8 kHz and 48 kHz and
use one of the interface protocols listed above. The
DCI automatically handles the interface timing
associated with these codecs. No overhead from the
CPU is required until the requested amount of data has
been transmitted and/or received by the DCI. Up to four
data words can be transferred between CPU interrupts.
The data word length for the DCI is programmable up
to 16 bits to match the data size of the dsPIC33F CPU.
However, many codecs have data word sizes greater
than 16 bits. Long data word lengths can be supported
by the DCI. The DCI is configured to transmit/receive
the long word in multiple 16-bit time slots. This
operation is transparent to the user and the long data
word is stored in consecutive register locations.
