HOLD acknowledge signal. An output signal sent to the HOLDA pin by the CPU in acknowledgement of a properly initiated HOLD operation.
When HOLDA is low, the processor is in a holding state and the address, data, and memory-control lines are available to external circuitry.

Horizontal blanking. A bidirectional horizontal timing signal that enables or disables pixel capture and display. HBLNK occurs once per line and has a pulse width defined as an integral number of frame clock (FCLK) periods. See also blanking pulse.
Industry:Semiconductors
The second phase of the pipeline; the phase in which the instruction is decoded. See also pipeline.

I/O space select pin. The DSP asserts IS to indicate an access to external I/O space.
Industry:Semiconductors
The second stage of the master processor’s fetch, execute, access (FEA) pipeline and the third stage of the parallel processor’s fetch, address, execute (FAE) pipeline. These stages operate differently for the master processor and the parallel processors. For the master processor’s execute stage, the instruction is decoded, source operands are read from the registers, the operation is performed, and the results are written into the destination register. For the parallel processor, all data unit operations occur, as well as memory accesses (loads and stores) and register-to-register moves.
Industry:Semiconductors
I/O-space wait-state bit(s). A value in the wait-state generator control register (WSGR) that determines the number of wait states applied to reads from and writes to off-chip I/O space. On the ’C209, ISWS is bit 2 of the WSGR; on other ’C2xx devices, ISWS is bits 11–9.
Industry:Semiconductors
The series of scan lines that comprise a television picture or a computer’s display. A raster line is the same as a scan line, which is an individual sweep across the face of the display by the electron beam that makes the picture.
Industry:Semiconductors
Improvement in the execution speed of a programme or in the reduction of the size of C programs.
Industry:Semiconductors
The signal generated by the frame timers that can be used to define a special area, such as an overscan boundary. This signal acts identically in both interlaced and noninterlaced modes, defining a purely rectangular region.
