Register Nomenclature  
TABLE 1-3:  
REGISTER NOMENCLATURE  
Register Bit Type Notation  
Register Bit Description  
R
W
Read: A register or bit with this attribute can be read.  
Read: A register or bit with this attribute can be written.  
Read only: Read only. Writes have no effect.  
RO  
WO  
WC  
WAC  
RC  
LL  
Write only: If a register or bit is write-only, reads will return unspecified data.  
Write One to Clear: Writing a one clears the value. Writing a zero has no effect  
Write Anything to Clear: Writing anything clears the value.  
Read to Clear: Contents is cleared after the read. Writes have no effect.  
Latch Low: Clear on read of register.  
LH  
Latch High: Clear on read of register.  
SC  
Self-Clearing: Contents are self-cleared after the being set. Writes of zero have no  
effect. Contents can be read.  
SS  
Self-Setting: Contents are self-setting after being cleared. Writes of one have no  
effect. Contents can be read.  
RO/LH  
Read Only, Latch High: Bits with this attribute will stay high until the bit is read. After it  
is read, the bit will either remain high if the high condition remains, or will go low if the  
high condition has been removed. If the bit has not been read, the bit will remain high  
regardless of a change to the high condition. This mode is used in some Ethernet PHY  
registers.  
NASR  
Not Affected by Software Reset. The state of NASR bits do not change on assertion  
of a software reset.  
RESERVED  
Reserved Field: Reserved fields must be written with zeros to ensure future compati-  
bility. The value of reserved bits is not guaranteed on a read.
