Hello,
I try to use a quad uart sc28c94.
I don't arrive to manage the power down/ up.
On a Duart SC28L92 there was commands 0xEx and 0xFx to do that.
On the 28c94 there are 2 registers 0x24 and 0x25 for power down and power up.
Into the data sheet is marked that you have to write on it.
I wrote 0x00 it doesn't works I tried to write bytes with a bit = 1 in all position 0 to 7 It
doesn't works. ( 00000001 00000010 ... 10000000 )
What have I to write to activate this functions ?
It is marked that there are a application note to put the quad uart into a ultra low power down 5µA I cannot find this application note. Did anybody know where I can download it ?
Did anybody have a address where I can find a soft example ?
Thank you
Marius
