Read Only bit(s). Writes to these bits have no effect. These are static values
only.
Read Only/Volatile bit(s). Writes to these bits have no effect. These are
status bits only. The value to be read may change based on internal events.
Read Only/Volatile/Sticky bit(s). Writes to these bits have no effect.
These are status bits only. The value to be read may change based on internal
events. Bits are not returned to their default values by “warm” reset, but will
be reset with a cold/complete reset.
Atomic Flag bit(s). The first time the bit is read with an enabled byte, it
returns the value 0, but a side-effect of the read is that the value changes to
1. Any subsequent reads with enabled bytes return a 1 until a 1 is written to
the bit. When the bit is read, but the byte is not enabled, the state of the bit
does not change, and the value returned is irrelevant, but will match the state
of the bit.
When a 0 is written to the bit, there is no effect. When a 1 is written to the bit,
its value becomes 0, until the next byte-enabled read. When the bit is written,
but the byte is not enabled, there is no effect.
Conceptually, this is “Read to Set, Write 1 to Clear”
Read/Write bit(s). These bits can be read and written by software.
Hardware may only change the state of this bit by reset.
Read/Write 1 to Clear bit(s). These bits can be read. Internal events may
set this bit. A software write of 1 clears (sets to ‘0’) the corresponding bit(s)
and a write of 0 has no effect.
Read/Write 1 to Clear/Lockable/Sticky bit(s). These bits can be read.
Internal events may set this bit. A software write of 1 clears (sets to ‘0’) the
corresponding bit(s) and a write of 0 has no effect. Bits are not cleared by
“warm” reset, but will be reset with a cold/complete reset. Additionally there
is a Key bit (which is marked RW-K or RW-L-K) that, when set, prohibits this
bit field from being writeable (bit field becomes Read Only/Volatile).
