3-2. Description of Electric System
(6) 7-segment LED (ND1) (Refer to Fig. 3-2-1.)(8) Buffer (IC28, IC30, IC31, IC32, and IC33)
(Refer to Fig. 3-2-1.)
The CPU-107 board mounts a 7-segment LED (ND1) that
indicates the state of a CPU (IC5). This LED is controlledThe CPU-107 board is connected to the bus on the
by a D-type flip-flop circuit (IC20 and IC22). The displaymotherboard via this bus buffer (IC28, IC30, IC31, IC32,
data output from the CPU (IC5) is latched by IC20 andand IC33: 3-stage buffer and line driver).
IC22 and displayed by the LED (ND1).
(9) Memory map (Refer to Table 3-2-1.)
(7) Inport (IC17, IC19, and IC24)
(Refer to Fig. 3-2-1.)The memory map on the CPU-107 board is shown below.
IC17, IC19, and IC24 are a 3-stage non-inverting buffer
that reads the set value of DIP switches (S4 and S5) and
rotary switch (S6).
