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 TXREQ<31:16>: Message Send Request bits
TXEN =
1 (object configured as a transmit object):
Setting this bit to ‘1’ requests sending a message. The bit will automatically clear when the message(s)
queued in the object is (are) successfully sent. This bit can NOT be used for aborting a transmission.
TXEN =
0 (object configured as a receive object):
This bit has no effect.
