Semiconductor
MSM80C88A-10RS/GS/JS
TEST
TEST: Input
This line is examined by a "WAIT" instruction.
When TEST is high, the CPU enters an idle cycle.
When TEST is low, the CPU exits in an idle cycle.
NMI
NON MASKABLE INTERRUPT: Input
This line causes a type 2 interrupt.
NMI is not maskable.
This signal is internally synchronized and needs 2-clock cycle pulse width.
RESET
RESET:Input
This signal causes the CPU to initialize immediately.
This signal is active high and must be at least four clock cycles.
CLK
CLOCK: Input
This signal provides the basic timing for the internal circuit.
MN/MX
MINIMUM/MAXIMUM: Input
This signal selects the CPU’s operating mode.
When VCC is connected, the CPU operates in minimum mode.
When GND is connected, the CPU operates in maximum mode.
VCC
VCC: +5V supplied.
GND
GROUND
The following pin function descriptions are for maximum mode only. Other pin functions are
already described.
SO, S1, S2
STATUS: Output
These lines indicate bus status and they are used by the MSM82C88-2 Bus Controller to
generate all memory and I/O access control signals. These lines are high impedance during
hold acknowledge. These status lines are encoded as shown below.
