bit 7 bit 0
Legend:
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 15-0 TXQUA<31:16>: TXQ User Address bits
A read of this register will return the address where the next message is to be written (TXQ head).
Note 1: This register is not ensured to read correctly in Configuration mode and should only be accessed when the
module is not in Configuration mode.
