The ispPAC-POWR6AT6 contains trim detection processing circuitry to signal when closed-loop trimming is com-
plete for selected trim output pins. This signal is output on the closed-loop control output pin (CLTLOCK/SMBA)
which has a open drain output and is normally asserted low (pull down). When all closed-loop trim output pins
reach a completion or trim “locked” condition, the CLTLOCK/SMBA output pin pulls low. Afterwards, the CLTLOCK/
SMBA pin also indicates when a trimming fault exists by de-asserting (going high). Finally, the CLTLOCK/SMBA pin
can be con?gured to work in conjunction with the SMBus Alert protocol to signal when trim lock has been achieved
or lost (see the section on SMBus Alert for details).
Figure 3-21 shows a simpli?ed diagram of how the state of the CLTLOCK/SMBA output pin is generated. After
closed loop trimming is enabled, the CLTLOCK/SMBA signal processing logic examines the output result from the
ADC going to each TrimCell at the end of each trim update cycle. If it is determined that a trim lock condition exists
for that trim output pin, the trim lock signal is asserted. The status of an individual trim output can be read via the
I 2 C closed loop trim register (refer to Figure 3-15). Trim output pins not selected for closed-loop trim operation will
automatically indicate a trim locked condition.

Next, an individual lock signal is OR'd with an E 2 CMOS mask bit speci?c to that trim output pin. There are six mask-
ing bits, one for each possible trim output pin. When set, masking bits effectively override the lock determination for
a particular trim output pin. The default setting for all mask bits is cleared (not set). Changes to the device con?gu-
ration mask bits can be made using PAC-Designer.
