FULL
(stack full)
The active low output FULL indicates that 9 items have
been loaded onto the stack .
PL
,
MAP
&
VECT
(pipeline, map and vector)
These active low outputs are set according to the
instruction being executed. At any time only one is active.
They may be used to select from one of three possible
external sources for microprogramme jumps, being used
directly as three-state enables for these sources.
Typically:
PL
enables the primary source of
microprogramme jumps, usually part of a pipeline register;
MAP
enables a PROM which maps an instruction to a
microcode starting location;
VECT
enables an optional third
source, after a vector from DMA or interrupt source.
Y (0 to 11) (Microcode address)
This is a 12 bit wide tristate output bus. It carries the
microcode address generated according to the instruction
read in from the I bus. OE can be used to put the bus in a high
impedance state. This allows another to take control of the
microcode address bus.
OE
(Output enable)
This active low input is used to enable the 12 lines of the Y
bus.
CP (Clock Pulse)
A LOW-to-HlGH transition on this input is used to trigger all
state changes within the device.
