outputs of the block and consequently the device outputs (refer to the "Test
Mode 0 Details" in the "Test Features" section).HIZIO,HIZDATA:
The HIZIO and HIZDATA bits control the tristate modes of the E1XC . While
the HIZIO bit is a logic 1, all output pins of the E1XC except the data bus are
held in a high-impedance state. The microprocessor interface is still active.
While the HIZDATA bit is a logic 1, the data bus is also held in a high-
impedance state which inhibits microprocessor read cycles.
