XGATE Software Trigger Register (XGSWT)
The eight software triggers of the XGATE module can be set and cleared through the XGATE Software
Trigger Register (
). The upper byte of this register, the software trigger mask, controls the
write access to the lower byte, the software trigger bits. These bits can be set or cleared if a "1" is written
to the associated mask in the same bus cycle. Refer to
Section 10.5.2, “Outgoing Interrupt Requests
for
further information.
