CCBs

87C196CB SUPPLEMENT

CAN

Controller area network. The 87C196CB’s integrated

 

networking peripheral, similar to Intel’s standalone

 

82527 CAN serial communications controller, that

 

supports CAN specification 2.0.

CCBs

Chip configuration bytes. The chip configuration

 

registers (CCRs) are loaded with the contents of the

 

CCBs after a device reset, unless the device is

 

entering programming modes, in which case the

 

PCCBs are used.

CCRs

Chip configuration registers. Registers that specify

 

the environment in which the device will be

 

operating. The chip configuration registers are loaded

 

with the contents of the CCBs after a device reset

 

unless the device is entering programming modes, in

 

which case the PCCBs are used.

channel-to-channel matching error

The difference between corresponding code

 

transitions of actual characteristics taken from

 

different A/D converter channels under the same

 

temperature, voltage, and frequency conditions. This

 

error is caused by differences in DC input leakage and

 

on-channel resistance from one multiplexer channel

 

to another.

characteristic

A graph of output code versus input voltage; the

 

transfer function of an A/D converter.

clear

The “0” value of a bit or the act of giving it a “0”

 

value. See also set.

code

1) A set of instructions that perform a specific

 

function; a program.

 

2) The digital value output by the A/D converter.

code center

The voltage corresponding to the midpoint between

 

two adjacent code transitions on the A/D converter.

code transition

The point at which the A/D converter’s output code

 

changes from “Q” to “Q+1.” The input voltage corre-

 

sponding to a code transition is defined as the voltage

 

that is equally likely to produce either of two adjacent

 

codes.
