Non-Return to Zero
Two level encoding used to transmit data over a communications medium. A bit value of '1' indi-
cates a high voltage signal. A bit value of '0' indicates a low voltage signal. The data line defaults
to a high level.
NRZ

Opcode
The portion of the 14-bit instruction word that specifies the operation that needs to occur. The
opcode is of variable length depending on the instruction that needs to be executed. The opcode
varies from 4-bits to x-bits. The remainder of the instruction word contains program or data mem-
ory information.
Oscillator Start-up Timer (OST)
This timer counts 1024 crystal/resonator oscillator clock before releasing the internal reset sig-
nal.
