HAL Component — SELECTN
INSTANTIABLE COMPONENTS — General
All instantiable components can be loaded in two manners
Using loadrt with or without count= | names= parameters as per legacy components
Using newinst, which names the instance and allows further parameters and arguments
primarily pincount= which can set the number of pins created for that instance (where applicable)
NAME
selectn — select one of n
SYNOPSIS
selectn
USAGE SYNOPSIS
loadrt selectn
OR
newinst selectn <newinstname> [ pincount=N | iprefix=prefix ] [instanceparamX=X | argX=X ]
( args in [ ] denote possible args and parameters, may not be used in all components )
FUNCTIONS
selectn.N.funct ( OR <newinstname>.funct )
PINS
selectn.N.enable bit io (default: true) ( OR <newinstname>.enable bit io (default: true) ) - Set enable to false to cause all outputs to be set false
selectn.N.sel s32 in ( OR <newinstname>.sel s32 in ) - The number of the output to set true. All other outputs well be set false
selectn.N.out%01d bit out (M=0..pincount) ( OR <newinstname>.out%01d bit out (M=0..pincount) ) - Output bits. If enable is set and the sel input is between 0 and 7, then the corresponding output bit will be set true
INST_PARAMETERS
pincount int (default: 2)
