Legend: P = Programmable bit
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31-16 Unimplemented: Read as ‘0’
bit 15-8 STNADDR4<7:0>: Station Address Octet 4 bits
These bits hold the fourth transmitted octet of the station address.
bit 7-0 STNADDR3<7:0>: Station Address Octet 3 bits
These bits hold the third transmitted octet of the station address.
Note 1: Both 16-bit and 32-bit accesses are allowed to these registers (including the SET, CLR and INV registers).
8-bit accesses are not allowed and are ignored by the hardware.
2: This register is loaded at reset from the factory preprogrammed station address.
