|
* values. The hope is that the BIOS has done the right |
|
* thing (which is why the default is reset=0, init=0), |
|
* but if not, reset is the hard hammer and init |
|
* is the soft mallet both of which are trying to whack |
|
* things into place... |
|
* NOTE: The data sheet makes a distinction between |
|
* "power on defaults" and "reset by MR". As far as I can tell, |
|
* the hard reset puts everything into a power-on state so I'm |
|
* not sure what "reset by MR" means or how it can happen. |
