REGISTER DESCRIPTION (Cont’d)
COMPARE RESULT REGISTER (CRR)
R243 - Read/Write
Register Page: 63
Reset Value: 0000 xxxx (0xh)
Two adjacent channels (identified as A and B) can
be selected through CLR1 register programming
(bits CC[3:0]); a level window for the converted an-
alog input can be defined on these channels.
Bits 7 = CBU: Compare Register Ch. B Upper
Threshold
Set when converted data on channel B is greater
than the threshold value set in UTBHR/UTBLR
registers.
Bits 6 = CAU: Compare Register Ch. A Upper
Threshold
Set when converted data on channel A is greater
than the threshold value set in UTAHR/UTALR
registers.
Bits 5 = CBL: Compare Register Ch. B Lower
Threshold
Set when converted data on channel B is less than
the threshold value set in LTBHR/LTBLR regis-
ters.
Bits 4 = CAL: Compare Register Ch. A Lower
Threshold
Set when converted data on channel A is less than
the threshold value set in LTAHR/LTALR regis-
ters.
Bits 3:0 = Don’t care
LOWER THRESHOLD REGISTERS (LTiHR/
LTiLR)
The two pairs of Lower Threshold High/Low regis-
ters are used to store the user programmable low-
er threshold 10-bit values, to be compared with the
current conversion results, thus setting the lower
window limit.
