87C196CB SUPPLEMENT

FET

Field-effect transistor.

frequency generator

The 8XC196MD peripheral that generates outputs

 

with a fixed 50% duty cycle and a programmable

 

frequency. The frequency generator can be used for

 

infrared transmission.

full-scale error

The difference between the ideal and actual input

 

voltage corresponding to the final (full-scale) code

 

transition of an A/D converter.

hold latency

The time it takes the microcontroller to assert HLDA#

 

after an external device asserts HOLD#.

ideal characteristic

The characteristic of an ideal A/D converter. An ideal

 

characteristic is unique: its first code transition occurs

 

when the input voltage is 0.5 LSB, its full-scale (final)

 

code transition occurs when the input voltage is 1.5

 

LSB less than the full-scale reference, and its code

 

widths are all exactly 1.0 LSB. These properties result

 

in a conversion without zero-offset, full-scale, or

 

linearity errors. Quantizing error is the only error

 

seen in an ideal A/D converter.

input leakage

Current leakage from an input pin to power or ground.

input series resistance

The effective series resistance from an analog input

 

pin to the sample capacitor of an A/D converter.

integer

Any member of the set consisting of the positive and

 

negative whole numbers and zero.

INTEGER

A 16-bit, signed variable with values from –2 15

 

through +215–1.

interrupt controller

The module responsible for handling interrupts that

 

are to be serviced by interrupt service routines that

 

you provide. Also called the programmable interrupt

 

controller (PIC).

interrupt latency

The total delay between the time that an interrupt is

 

generated (not acknowledged) and the time that the

 

device begins executing the interrupt service routine

 

or PTS routine.

interrupt service routine

A software routine that you provide to service a

 

standard interrupt. See also PTS routine.

interrupt vector

A location in special-purpose memory that holds the

 

starting address of an interrupt service routine.
