Mode selection for Reset.
Description
Reset input. Active low.
Initializes the 950-Core to the Reset state.
Low power input. Active low.
When low, forces reset address to 0x0000.
When high, forces reset address to 0xFC00.
Description
Emulator halt request. Active low.
Halts program execution and enters emulation mode.
Output flag asserted high when the processor is halted due to an emulation
halt request or a valid breakpoint condition.Asserted low when the proces-
sor is not Halted or during execution of an instruction under control of the
emulator.
Halt acknowledge. Active high.
Asserted high when the processor is halted from an Emulator Halt request
or when a valid Breakpoint condition is met.
Snapshot. Active high.
Asserted high when executing an instruction if Snapshot mode is enabled.
Description
Test data input.
Test clock.
Test mode select.
Test data output.
Test logic reset (also used for Emulator module). Active low.
