HIZIO:
HIZDATA:
The HIZIO bit controls the tri-state modes of the output pins of the TEMAP-
84. While the HIZIO bit is a logic 1, all output pins of the TEMAP-84, except
the data bus, are held in a high-impedance state. The microprocessor
interface is still active.
The HIZDATA bit controls the tri-state modes of the TEMAP-84. While the
HIZIO bit is a logic 1, all output pins of the TEMAP-84, except the data bus,
are held in a high-impedance state. While the HIZDATA bit is a logic 1, the
data bus is held in a high-impedance state which inhibits microprocessor read
cycles.
