92 SBC329 3U VPX Single Board Computer
Publication No. SBC329-HRM/1
6.15.7
VPX GDISC1 Both Edges Register (0x68E)
Bit 7 sets both-edge mode for the GDISC1 pin, as follows:
1 =Both-edge mode enabled
0 =Both-edge mode disabled (default)
When enabled, both-edge mode causes interrupts to be generated on both rising and
falling edges. The GDISC1 bit must be in edge mode for both-edge mode to work.
6.15.8
VPX GDISC1 Interrupt Status Register (0x68F)
Bit 7 shows the status of the GDISC1 pin, as follows:
1 =Interrupt pending
0 =No interrupt (default)
Write a ‘1’ to bit 7 to clear the inte
rrupt.
6.15.9
VPX GDISC1 Availability Register (0x690)
Bit 7 shows the availability of the GDISC1 pin, as follows:
1 =GDISC1 is available
0 =GDISC1 is not available (default)
6.16 Ethernet Port Availability Register (0x6A0)
Availability of Ethernet ports 0 to 2 is build option dependent.
NOTE
Even when a port is not available due to a build option, it may still be visible to software.
