21.1
Fundamental Operation
The CWG generates a two output complementary
waveform from one of four selectable input sources.
The off-to-on transition of each output can be delayed
from the on-to-off transition of the other output, thereby,
creating a time delay immediately where neither output
is driven. This is referred to as dead time and is covered
operating waveform, with dead band, generated from a
single input signal is shown in Figure 21-2.
It may be necessary to guard against the possibility of
circuit faults or a feedback event arriving too late or not
at all. In this case, the active drive must be terminated
before the Fault condition causes damage. This is
referred to as auto-shutdown and is covered in
21.2
Clock Source
The CWG module allows for up to 2 different clock
sources to be selected:
Fosc (system clock)
HFINTOSC (16 MHz only)
The clock sources are selected using the G1CS0 bit of
the CWGxCON0 register (Register 21-1).
21.3
Selectable Input Sources
The CWG uses four different input sources to gener-
ate the complementary waveform:
PWM1
PWM2
N1OUT
LC1OUT
The input sources are selected using the GxIS<1:0>
bits in the CWGxCON1 register (Register 21-2).
21.4
Output Control
Immediately after the CWG module is enabled, the
complementary drive is configured with both CWGxA
and CWGxB drives cleared.
21.4.1
OUTPUT ENABLES
Each CWG output pin has individual output enable
control. Output enables are selected with the GxOEA
and GxOEB bits of the CWGxCON0 register. When an
output enable control is cleared, the module asserts no
control over the pin. When an output enable is set, the
override value or active PWM waveform is applied to
the pin per the port priority selection. The output pin
enables are dependent on the module enable bit,
GxEN. When GxEN is cleared, CWG output enables
and CWG drive levels have no effect.
21.4.2
POLARITY CONTROL
The polarity of each CWG output can be selected
independently. When the output polarity bit is set, the
corresponding output is active high. Clearing the output
polarity bit configures the corresponding output as
active low. However, polarity does not affect the
override levels. Output polarity is selected with the
GxPOLA and GxPOLB bits of the CWGxCON0 register.
21.5
Dead-Band Control
Dead-band control provides for non-overlapping output
signals to prevent shoot-through current in power
switches. The CWG contains two 6-bit dead-band
counters. One dead-band counter is used for the rising
edge of the input source control. The other is used for
the falling edge of the input source control.
Dead band is timed by counting CWG clock periods
from zero up to the value in the rising or falling dead-
band
counter
registers.
See
CWGxDBR
and
CWGxDBF registers (Register 21-4 and Register 21-5,
respectively).
21.6
Rising Edge Dead Band
The rising edge dead band delays the turn-on of the
CWGxA output from when the CWGxB output is turned
off. The rising edge dead-band time starts when the
rising edge of the input source signal goes true. When
this happens, the CWGxB output is immediately turned
off and the rising edge dead-band delay time starts.
When the rising edge dead-band delay time is reached,
the CWGxA output is turned on.
The CWGxDBR register sets the duration of the dead-
band interval on the rising edge of the input source
signal. This duration is from 0 to 64 counts of dead band.
Dead band is always counted off the edge on the input
source signal. A count of 0 (zero), indicates that no
dead band is present.
If the input source signal is not present for enough time
for the count to be completed, no output will be seen on
the respective output.
