22.11 Configuring the CWG
The following steps illustrate how to properly configure
the CWG to ensure a synchronous start:

Ensure that the TRIS control bits corresponding
to CWGxA and CWGxB are set so that both are
configured as inputs.
Clear the GxEN bit, if not already cleared.
Set desired dead-band times with the CWGxDBR
and CWGxDBF registers.
Setup the following controls in CWGxCON2
auto-shutdown register:
Select the desired input source using the
CWGxCON1 register.
Configure the following controls in CWGxCON0
register:
Set the GxEN bit.
Clear TRIS control bits corresponding to
CWGxA and CWGxB to be used to configure
those pins as outputs.
If auto-restart is to be used, set the GxARSEN
bit and the GxASE bit will be cleared automati-
cally. Otherwise, clear the GxASE bit to start the
CWG.

override level and GxASDLB controls the CWG1B
override level. The control bit logic level corresponds to
the output logic drive level while in the shutdown state.
The polarity control does not apply to the override level.
22.11.2
After an auto-shutdown event has occurred, there are
two ways to have resume operation:
• Software controlled
• Auto-restart
The restart method is selected with the GxARSEN bit
of the CWGxCON2 register. Waveforms of software
controlled and automatic restarts are shown in
Figure 22-5
22.11.2.1
When the GxARSEN bit of the CWGxCON2 register is
cleared, the CWG must be restarted after an auto-shut-
down event by software.
Clearing the shutdown state requires all selected shut-
down inputs to be low, otherwise the GxASE bit will
remain set. The overrides will remain in effect until the
first rising edge event after the GxASE bit is cleared.
The CWG will then resume operation.
22.11.2.2
When the GxARSEN bit of the CWGxCON2 register is
set, the CWG will restart from the auto-shutdown state
automatically.
The GxASE bit will clear automatically when all shut-
down sources go low. The overrides will remain in
effect until the first rising edge event after the GxASE
bit is cleared. The CWG will then resume operation.
