Configuration 3
Notes
0) CR22 Bit 5 is reset on Vtr POR only
1) This register contains some bits which are read or write only.
2) Register 60 is the high byte; 61 is the low byte. For example to set the primary base address to
1234h, write 12h into 60, and 34h into 61.
3) These configuration registers are powered by Vtr and battery backed up.
4) The Activate bit for Logical Device A does not effect the generation of an interrupt (SCI).
