NOTE
Suggested Mnemonics for accessing the interrupt flag vector on a word
basis are:
XGIF_7F_70 (XGIF[127:112]),
XGIF_6F_60 (XGIF[111:96]),
XGIF_5F_50 (XGIF[95:80]),
XGIF_4F_40 (XGIF[79:64]),
XGIF_3F_30 (XGIF[63:48]),
XGIF_2F_20 (XGIF[47:32]),
XGIF_1F_10 (XGIF[31:16]),
XGIF_0F_00 (XGIF[15:0])
10.3.1.9 XGATE Software Trigger Register (XGSWT)
The eight software triggers of the XGATE module can be set and cleared through the XGATE Software
Trigger Register (Figure 10-11). 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.
