Description
This bit or bit field can be written or read.
This bit or bit field is read only.
This bit or bit field is write only (read as 0_H).
As rw, but bit or bit field can also be modified by hardware.
As r, but bit or bit field can also be modified by hardware.
Bits with this attribute are “sticky” in one direction. If their reset value
is once overwritten they can be switched again into their reset state
only by a reset operation. Software and internal logic (except reset-
like functions) cannot switch this type of bit into its reset state by
writing directly the register. The sticky attribute can be combined to
other functions (e.g. ‘rh’).
Bit fields named ‘0’ indicate not implemented functions. They have
the following behavior:
• Reading these bit fields returns 0_H.
• Writing these bit fields has no effect.
These bit fields are reserved. When writing, software should always
set such bit fields to 0_H in order to preserve compatibility with future
products.
Certain bit fields or bit combinations in a bit field can be marked as
‘Reserved’, indicating that the behavior of the device is undefined for
that combination of bits. Setting the register to such an undefined
value may lead to unpredictable results. When writing, software must
always set such bit fields to legal values.
