10.11.2 Introduction
The Analog to Digital Converter (ADC) consists of
an input multiplex channel selector feeding a suc-
cessive approximation converter.
The conversion time depends on the INTCLK fre-
quency and the prescaler factor stored in the
PR[2:0] bits of the CLR2 register (R253-page 63)).
AV
ence voltage pins. Up to 16 multiplexed Analog In-
puts are available depending on the specific de-
vice type. With the AUTOSCAN feature, a group of
signals can be converted sequentially by simply
programming the starting address of the first ana-
log channel to be converted.
There are two Analog Watchdogs used for the
continuous hardware monitoring of two consecu-
tive input channels selectable by means of the
CC[3:0] bits in the CLR1 register (R252-page 63).
An Interrupt request is generated whenever the
converted value of either of these two analog in-
puts exceeds the upper or lower programmed
threshold values.
