dfsct
Description:
Defines three shortcuts applied to three predriver outputs among the set of all the low-
side and high-side predrivers.
The shortcuts table defines the connection between the physical outputs of the microcore
and the external outputs pin (G_HSx and G_LSx) driving the MOSFETs.
Note that in order to use the async or sync mode, the low-side use for DCDC has to be
set as shortcut 2 (ex: dfsct undef ls7 undef).
At reset the default shortcut setting is undefined
Assembler syntax:
dfsct Shrt1 Shrt2 Shrt3;
Operands:
•
Shrt1, Shrt2, and Shrt3 – Operands define to which predriver the shortcut is dedicated
