87C196CB SUPPLEMENT

nonlinearity

The maximum deviation of code transitions of the

 

terminal-based characteristic from the corre-

 

sponding code transitions of the ideal characteristic.

nonmaskable interrupts

Interrupts that cannot be masked (disabled) and

 

cannot be assigned to the PTS for processing. The

 

nonmaskable interrupts are unimplemented opcode,

 

software trap, and NMI.

nonvolatile memory

Read-only memory that retains its contents when

 

power is removed. Many MCS® 96 microcontrollers

 

are available with either masked ROM, EPROM, or

 

OTPROM. Consult the Automotive Products or

 

Embedded Microcontrollers databook to determine

 

which type of memory is available for a specific

 

device.

npn transistor

A transistor consisting of one part p-type material and

 

two parts n-type material.

off-isolation

The ability of an A/D converter to reject (isolate) the

 

signal on a deselected (off) output.

OTPROM

One-time-programmable read-only memory. Similar

 

to EPROM, but it comes in an unwindowed package

 

and cannot be erased.

p-channel FET

A field-effect transistor with a p-type conducting

 

path.

p-type material

Semiconductor material with introduced impurities

 

(doping) causing it to have an excess of positively

 

charged carriers.

PC

Program counter.

PCCBs

Programming chip configuration bytes, which are

 

loaded into the chip configuration registers (CCRs)

 

when the device is entering programming modes;

 

otherwise, the CCBs are used.

PIC

Programmable interrupt controller. The module

 

responsible for handling interrupts that are to be

 

serviced by interrupt service routines that you

 

provide. Also called simply the interrupt controller.
