9.4 Switches
9.4.1 RST Switch
The RST (RESET) switch can be used to generate a board reset.
A board reset is also performed at power-up.
A board reset can also be asserted by software programming the Utility Control Register.
A board reset will perform a general board hardware reset, re-configuration of the IP FPGA, PCI
reset and CPU reset.
If the TVME8240 is the VME bus system controller, a board reset will also trigger a VME bus
system reset.
9.4.2 ABT Switch
The ABT (ABORT) switch can be used to generate a CPU interrupt.
The Abort Switch is mapped to serial interrupt no. 1 of the MPC8240 EPIC. Serial interrupt no. 1
must be configured as edge sensitive.
