Datasheet
SMSC TMC2084
The NST feature as a network standard time allows multiple nodes to output the synchronous NST carry. It
is suitable for LED lamp controlling applications.
The carry output starts driving with High level when the devise comes out of reset. The condition for the pin
to start driving the carry output depends on the configuration of bits CMID3 – 0 as shown in the table
below:
(CM node) nNSTCOUT
(Node b) nNSTCOUT
(Node a) nNSTCOUT
nNSTCOUT (Clock)
nNSTCOUT (Pulse)
