4.16. I/O Page Register
Note:
For compatibility reasons, every undefined bit of a write register should be set to ‘0’. Undefined bits of a read
register should be treated as “don’t care”.

Reset
Function
all
00 H
During reset the control register is loaded with the contents of the address FFF9H, but it can be read and
written via software.
