- These commands are used to configure the host sleep parameters.
+gpiogap=[n], hscfgcmd
+ These commands are used to configure the host sleep parameters::
bit 8:0 -- Gap
bit 16:8 -- GPIO
where Gap is the gap in milli seconds between wakeup signal and
wakeup event, or 0xff for special host sleep setting.
